Getting My KTM 350 Ready For An Adventure Ride – May 2014

I previously reported on how to choose a dual-sport bike, and how I converted my KTM 350 xcf-w to a street legal dual-sport.  My next project was to enable my bike to carry camping gear so I can go on a multi-day adventure ride with friends and family. I did a lot of research via the Internet and talking to friends with adventure camping experience to help me in this quest.  This report summarizes the lessons I learned.

Camping Gear

My friend Bob has mastered minimalist adventure riding.  He can camp in comfort on his KTM 640 Adventure bike, but he also enjoys going super light on his KTM 300 two stroke.  When camping on his two stroke, he uses a tank bag and a backpack.

My friend Ross is at the other end of the spectrum.  He rides a KLR650 which we have dubbed the “super tanker”.  He is able to carry a lot of gear.

I intend to be somewhere in between.  I don’t want to be a minimalist.  At my age, with sleep apnea and recurring back problems, I want to camp in some degree of comfortable.  If I am miserable, I won’t want to go again.  But I also want my bike to be reasonably light and handle okay.

Most of my camping is done on multi-day river trips.  I often tell people that river running is a wilderness experience like backpacking – only we eat good.  Camping gear bulk and weight isn’t a big factor.  Therefore, most of my camping gear is too bulky and heavy to be used on an adventure ride.  I have gradually been trying to overcome that problem.

I started by buying a smaller tent.  Not super small, but small enough to fit nicely on my bike.  I really like the design of the Exped Gemini series tents.  I originally considered the 3-man tent, but decided to down size and bought the 2-man version once I found it on sale.

I already had a nice Big Agnes down sleeping bag, but the stuff sack is 8″ x 20″, which is way too big.  I bought a standard compression dry bag, but that made it about the size of a soccer ball, which didn’t fit in any of my pieces of luggage.  I then found an Exped compression sack that squishes the diameter of the bag rather than the length.  It now fits nicely in my Giant Loop Coyote bag or along side my tent in a dry bag.

I also picked up a Big Agnes Q-Core air mattress.  It is a little bulkier than I would like, but it is a lot smaller than my 3″ foam pad that I use on river trips.

Because of my back problems, I wanted a compact camp chair.  So last year I used my REI dividend to pick up an REI Flex Light chair.  I found this chair to be a little weak for my weight, so I will let my children use it.  I decided to buy the Big Agnes Helinox chair, with is a little stronger and wider.

I also needed compact cooking gear.  I ‘borrowed’ my son’s backpacking stove he got when in the Boy Scouts, and picked up a Soloist GSI cookset.  I think I now have enough gear to make this adventure dream become a reality.

Bike Modifications

One of the first questions is that of fuel range.  The stock 2.25 gallon tank would probably give me a range of close to 100 miles on a dual-sport type ride, but that probably isn’t enough.  I didn’t want a really big tank (especially when I can siphon gas off Ross with his super tanker), so I opted for a 3 gallon tank, giving me roughly a 150 mile range.

I first installed an Acerbis tank, but it has an offset fuel cap which made it really difficult to mount any of my tank bags.  The Enduro bag is small enough that it can work when mounted on an angle, but the other bags just didn’t work at all.

Acerbis offset fuel cap

So, I sold the Acerbis tank and bought a 3.1 gallon Clockworks tank.

Tank bag fit still isn’t ideal because of the volcano-like top – but it works.  In fact, the curved seat-to-tank allows the bottom of the tank bag to sag a little, giving me just a little more interior space.

Giant Loop Fandango tank bag

One of the downsides of the Clockworks tank is that it interferes with the thermostat.  I ended up spending more money to buy some thermostat bypass hoses.  And then after a few months of use, the banjo bolt fuel line connector started leaking.  So, I decided to buy the KTM 13L tank (~3.5 gallons).  I should have just bought this one in the first place.  It mounts up really easily, it has a low and centered fuel cap that uses the stock 1/4 turn fuel cap.

I bought a Wolfman E-12 saddle bag to use for both over-night and day trips. I was able to test it out on our recent ride of the White Rim trail in Canyonlands.  It was nice to get some weight out of our hydration packs for such a long ride, but the saddle bags filled up much quicker than I expected.  I was able to carry lunch for Jamie and I, as well as some tools.  The only time I even noticed it was there was when mounting or dismounting the bike.

But I encountered a problem throughout the day.  The lower mounting strap would slide up the frame, working its way in between two separate pieces of plastic.  This made it really difficult to get the bag mounted tight enough to not slide around.

I solved this problem by mounting a last tab on each side of the bike.  This required me to drill a small hole in each sub-frame member.  Hopefully that won’t cause a serious strength problem.

Lash tabs

The last tab allows me to really cinch down on the straps and get them super tight.

Update: On my first adventure ride I found that the right side Coyote bag rubbed on my leg but the left side did not.  This is because the right D-ring is further forward than the left.  To remedy this, I used a scrap of aluminum and built an offset bracket for the right D-ring.  My only concern is that my boot may snag on it.

Offset D-ring bracket

I also mounted some Footman Loops on the rear fender so the fender hooks would be more secure.  The molded edge of the KTM fender makes it difficult to get a secure fit with fender hooks.  This solved the problem very nicely.

Another crucial bike upgrade is a more comfortable seat.  I don’t mind the stock seat for trail riding, since I stand much of the time.  But for a dual-sport ride, the stock seat gets old really fast.

The thing that made me hesitate about selling the DRZ was the comfy Seat Concepts seat.  Ross suggested I just get a Seat Concepts seat for the KTM.  That was a great suggestion!

Seat Concepts

I tested out the new seat on a single track ride last weekend.  I was surprised at how much I loved it even on a technical ride.  It is so much more comfortable than the stock seat.  I am sure that my rear end will still get tired on a long dual-sport ride, but this should be a lot better than stock.

I also intend to change the gearing for dual-sport rides.  The XCF-W comes with 13/52 stock final gearing, while the street legal EXC comes with 14/45.  My intent is to split the difference and change the front sprocket to a 14T, giving me 14/52 gearing (which is standard on the EU/AU models).  I can do this without modifying the chain length.

With the 13/52 gearing, I find that at about 45 mph I want to shift up to a higher gear.  I can ride comfortably at about 55 mph, and for a short time I can push it to 65 mpg.  The bike will go much faster, but the motor is really wrapped up.  The 14/52 gearing ought to bump each of those numbers up by almost 5 mph.

Update: The 14/52 gearing worked pretty well for an adventure ride as long as I didn’t need to go faster than 60 mph.  One my first adventure, I had to ride down a canyon with traffic that was going 65 mph in spots.  I could do 65, but it was really pushing the bike and I was beyond my comfort zone.

This got me wondering why I can easily go 75 mph with my Husaberg FE-450.  I thought it had the same transmission as my 350, and it also has stock 13/52 sprockets.  So, I added the Husaberg to my spreadsheet as well as the primary gear.  I was surprised to learn that the FE-450 had a wider spread on the gears AND a taller primary gear.

Gear ratios compared with my Husaberg

Notice that the Husaberg’s 1st gear is almost as tall as the 350 EXC and 6th gear is even taller.  I was surprised that 1st was geared so high.  I guess the 450 has the power to pull such a tall gear.  But this clearly explains why I can do 75 on the Husaberg but not on my 350.

I also tried the 14/52 gearing on some single track.  It worked fine in the easy sections, and gave me a comfortable riding speed in 2nd gear.  But it was noticeably harder to loft the front end, and I was wanting quicker power response on long, steep climbs.  13/52 is definitely better for tight trails (for me anyway).

The bottom line is that the 14/52 gearing is a reasonable compromise.  You loose some power for steep climbs and lofting the front end, but you pick up some top end for the pavement.  I prefer the stock 13/52 for pure trail riding.

Update 2: After further evaluation my daughter and I both concluded that 1st gear with the 13/52 sprockets is too low.  On long steep climbs we were always wanting something in between 1st and 2nd gear.  But I also found that 1st with the 14/52 gearing (which is roughly equivalent to 13/48) was too tall.  Thus, I have concluded that for technical trail riding 13/50 gearing would be more appropriate.  Based on significant Internet research, this seems to be a very popular choice.

So my plan going forward is to use 13/50 for technical trail riding (which is what I do most of the time).  This should give me a more usable 1st gear for trail riding.  For multi-day adventure rides, where we tend to cover a lot of ground but avoid very technical trails, I will change to 14/50 gearing.  This should give me a more comfortable ride at 65 mph.  It is also worth noting that regardless of the gearing, going above 65 mph on such a light bike – especially with knobby tires – is beyond my comfort zone.

Luggage Options

I have evaluated three different luggage options that work for bikes without a rear rack.  Read my report here.

Update – June 2014

I finally got to actually test my adventure setup.  We spent 3 days, 2 nights out in the Uinta mountains.  It turned out to be a pretty thorough test because we got rained on (while riding and camping), had cold temperatures, and hot temperatures.  We covered approximately 300 miles.  Here are some of my observations:

  • The 14/52 gearing worked quite well.  I could comfortably cruise at 55 mph and could hold 60 by pushing the bike a little.  I could do 65, but the bike was really tapped out and I wasn’t comfortable at that speed with knobby tires.  Now the question is whether this gearing will work for tight single track, or if I need to swap sprockets based on the type of ride.
  • For trail riding I like the extra power and lighter weight of the FMF 4.1 exhaust, but it is noticeably louder than the stock muffler.  So for dual-sport riding I decided to switch back to the stock can.  I mounted a Giant Loop exhaust shield on that can, so it will hopefully prevent my bags from melting.  The quieter sound was much appreciated on those long stretches of pavement, while driving through camp sites, or when approaching wildlife or horses.
  • I bought an A.R.C. Back Country Foul Weather jacket and pants so I wouldn’t have to carry rain gear.  The zipper vents worked quite well as long as you were moving.  When stopped, you can get pretty hot.  They also seemed to be 100% waterproof.  We rode through some pretty heavy rain and the water just beaded up on the surface.  I stayed perfectly dry.  For the price, they are a very good set.

  • I had my down jacket packed in a stuff sack inside the Coyote bag, making it too difficult to get to.  When the cold front came through it got pretty cold and it would have been nice to have that jacket handy.  Next time perhaps I will carry the jacket in my backpack.
  • The Seat Concepts seat exceeded my expectations.  It was very comfortable both on and off pavement.  It is much more comfortable than the stock KTM seat.

All in all it was a very fun experience and I was extremely pleased with the performance of my gear.  My tent, air pad, sleeping bag worked perfectly, as did my camp chair and kitchen setup.  I will make a few minor adjustments to the saddle bag mounting hardware, but for the most part things worked great.

  1. Excellent article. How did the 14/52 gearing work out? Thanks for the Acerbis tank, it’s working perfectly! Justin C.

    Great article and very comprehensive. I have often thought while riding ‘WOW this would be a great place to camp” if I could bring enough. But how could I. Thanks to you details I am now seriously considering trail riding camping. Love the information I will let you know what I come up with.

    Now let’s have “…the rest of the story…” Meaning a report on how it all worked and where you camped. 🙂

    Great write up. I just bought a 2016 KTM350exc and was wondering on far do you feel comfortable riding on the freeways/highways for long distances? Every thought of adding a higher wind screen for this?

    • For the most part I really love the 350. But high speed pavement is one place it is lacking. The larger 500 has a wider spread in the transmission, so it is better suited for pavement. But they are both really light bikes and are easily blown around by cross winds. I now use 13/50 sprockets for technical trail riding and 14/50 for dual-sport. It is kind of a pain to swap sprockets all the time, but with the 350 tranny it really makes a difference. With 13/50 gearing I can go about 55 mph without feeling that I am over-revving the bike. With 14/50 I can go about 60 mph. I can push it to 65 (or higher), but I don’t like to sustain it for very long. Maybe 14/45 would be comfortable at 65, but then 1st gear would be pretty weak in the dirt.

      So, in general I try to plan my routes so I never have to ride on the freeway. I also try to avoid major 65 mph roads as much as possible. A 5 mile stretch isn’t bad, but anything more than 20 miles gets old really fast. I am fine on twisty canyon roads where I can go as fast as the cars.

      I looked into getting a wind screen for my Husaberg FE450 but concluded it wasn’t worth it for me. Since I try to avoid pavement anyway, I don’t see it adding more value. Plus it seems to be a possible danger in a crash – it looks like it wants to cut you in half. I also fear that a small wind screen would just put all of the buffeting right on my head instead of on my chest.

    Great write up.

    I would like to know where you got the hook tab at? I checked my local Hardware stores and nothing.

    thnx

    • If you are talking about the fender hooks – they came with my luggage. My Giant Loop, Wolfman, and AltRider luggage all came with them. As did some of my fender bags. I suggest contacting Mike at OBR ADV Gear. I’ll bet he can point you in the right direction.

    How often do you do your oil changes. I want this bike badly but I have read that on the 350 its every 15 hours, which for adventure riding just seems crazy. I’d like to go out for a few days at a time an not have to worry about bringing oil with me. How has your experience been?

    • I worried about this too – but it really isn’t a problem for the type of rides I do. I posted this question in some of the forums and found many people go 1500 miles or more without changing oil. I typically change oil about every 20 hours. I switched from Motorex synthetic to Rotella T Triple because it is so much cheaper. I just change oil before each long trip and then don’t worry about it. The longest I have gone is six days and my oil seemed fine afterwards. I also did a four day trip that covered about 600 miles and the oil was fine. I wouldn’t hesitate to go 1500-2000 miles between changes if I had to. But if you plan on trips longer than about one or maybe two weeks long, this probably isn’t the right bike (for example, I would not want to ride my 350 from Utah to Alaska). But for the types of rides I do which are mostly dirt roads and ATV trails, the bike is perfect. I would worry more about keeping the air filter clean. If you plan a dusty ride, it might be worth getting some filter skins.

    Great Article!
    I too ride a 350 but exc-f model. I am hoping to ride half the Trans America Trail this summer with my son, which will take about two weeks and 2500 miles. I am wanting to camp the trail and be pretty much self sufficient except food and fuel. I have been researching bags, giant loop and Wolfman but this is the first I’ve heard of ALTRider. I read your luggage options report and it sounds like you really liked the ALTRider bags. Would it be your opinion that the ALTRider bags would be the way to go for long ride carrying a lot of luggage?

    • Of the three setups I have, the AltRider system is my favorite. It is nice that the bags are waterproof, but the main thing I like is the lack of zippers. Zippers can be a real pain when they get dirty. The GL Coyote bag is really hard to zip and unzip due to the curvature of the bag, but I think their newer model has been improved.

      If I were buying today, I am not sure what I would buy. I would seriously consider some of the newer Wolfman saddlebags – such as the Enduro Dry Saddlebags. My main complaint with the E-12 is that they are too small, and I have to put too much stuff in the top dry bag, which puts the weight too high. The 2017 model has some nice improvements over the 2016 Enduro Dry bag. One thing I like about the Wolfman products is the D-rings. It allows you to add extra dry bags, water bottles, or fuel bottles as needed. It looks like a nice setup.

      Since I wrote my article on luggage, I have added a 2L bag to the top of each side leg of the AltRider bag for tools and first aid kit. I have also added another small dry bag to the very back for my camp shoes. The more I go, the more gear gets added to my ‘must have’ list, so having more space would be nice.

      I have been watching YouTube videos of the TAT. The western half looks pretty interesting. I have fun on your trip with your son. It sons like a great adventure.
