WR250R - First impressions

It's about time that I commented on how this new toy is working out for me now that I have about 800km of mixed riding on it. Should be more, but hey--between work and uncooperative weather over the past few months, I've barely had enough free time to figure out if the insulated liner should be in my jacket or not on any given day.


Coming off my 2000 KLR, the WR is a big change in some ways yet surprisingly not a change in others. The much lower weight is the first obvious difference. This is a bike that you can not only stand up easily if you tip it over, you can actually lift it off the ground.  In fact, getting it home from the dealer was just a matter of removing the mirrors and three of us lying it on its side in the back of our Toyota van. (In case you're wondering, I would've ridden it home but it needed some fit adjustments to make that safe.) Not only does it lose 72 lbs over the KLR (370 vs. 298 lbs), it loses them in the right place: up high.

All that weight loss leads to the second big difference: a little 250 is surprisingly good at getting you up to speed. Sure, it's not quite as fast as the KLR and the lack of low-end grunt means you need to rev higher and Texas two-step the gears to get going, but overall I don't feel that I'm really missing out on a lot of go. Not enough to justify an extra 400cc, anyway.

Third: It's surprisingly comfortable at 120 km/hr. The engine is smooth, the wind is on my chest rather than buffeting my helmet, and wind noise is somewhat reduced over the KLR. In fact, I've found the bike to be more stable when passing semis coming in the opposite lane of 2-lane highways. Maybe it's because there's so much less bike in the wind yet just enough stabilizing mass that it strikes some magic stability compromise. This was totally unexpected.

On the road it's a delightful toy to fling around corners and traffic. In my limited off-roading so far, it's proven to be remarkably capable through the ruts and puddles. Even a few laps in a sandy motocross pit was a blast. Basically, it's like my mountain bike with an engine. Such fun.


Mods
To really test the bike's capabilities, I need to upgrade the stock Deathwing tires to something more credibly dualsport-like. The D606 seems pretty popular on the rear and I'm also looking into a DOT-rated trials tire combo which will likely require a sprocket change. Reports on this strategy have been positive across a wide range of riding conditions. The bonus is that the less aggressive trials tread pattern has minimal impact on the trail without sacrificing performance. I just need to find a Canadian supplier of these tires.

Two immediate mods were the addition of a Flatland Racing skid plate and rad protector. For some reason the bike was missing the OE skid plate. No matter; it's pretty much junk anyway and doesn't protect the lower sides of the engine. Installing the Flatland was fairly straightforward once I figured out  exactly where to stick the weatherstripping between the parts that contact the frame, to reduce noise. Made a big difference. The rad guard is also highly recommended given the fragility (although not as bad as on the KLR) of the existing plastic. Both can be ordered from the helpful staff at MX1 in Vancouver. Next up will be proper bark busters.





Lack of carrying space is a minor issue, especially since the smaller tank only gives me about a 200 km range. This is still pretty impressive fuel economy out of a 7.2 L tank. One option is to go with a larger IMS tank. That's a lot of dough, so for now I've bungied a 5L fuel can on the back fender when needed. However, I recently drew up plans for a 9.5" x 13.25" aluminum rack which a local shop will water jet cut for me. It'll mount with four bolts into the subframe and be drilled to accept a RotoPax mount. Coincidentally, the RotoPax 1gal can is exactly the right size! I just have to make a few tweaks to my drawing and then I'll send the file to be cut from 6mm 6061 aluminum. Nothing fancy...once I see how it works, I'll probably tweak the design and extend it to allow for side racks bolted to the pillion foot peg mounts. Then I can mount soft bags.


So overall I'm very impressed with the WR and can't wait to try some longer rides on my upcoming vacation. If I was to ask for any improvements, it would be for a slightly larger stock tank and maybe another 100 cc of engine. Someone needs to offer a 300-400cc dualsport that can handle baggage no problem, and the WR would be the perfect platform for it.

Here's another ride review which agrees well with my experience.  

And if you're Jonesing for a real mountain adventure, check out this video of Black Bear Pass in Colorado, near where I was mountain biking with a buddy several years ago. This is epic riding country--motorized or not--and well worth a trip if you're looking for an interesting and accessible destination in North America.

New ride!

Last week I sold my KLR, and as luck would have it, the perfect bike came up for sale at a great price. Behold my new WR250R (not exactly as shown--mine's a 2009 and I never looked so stylish). This will be a wonderful wee beast for exploring the more technical trails out in Lanark County.

Initial ride impressions at the dealer were "wow". It's a major change from the fix-it-with-a-rock-and-screwdriver, tank-like feel of the KLR. EFI, about 60 bs lighter, supple suspension, and a much tighter cockpit make the bike feel more like a mountain bike with engine. I'm going to have to learn to ride all over again.

Lots of plans for this bike. First will be a larger tank to enable the typical back-country trek distances around here. I will fabricate a skid plate and some other doodads as well. ADVRider has an epic thread on mods to the bike, so no shortage of ideas. I'm also keen to try adapting some LED headlights to provide more flood. The lights I use for night riding on my mtn bike make it almost as good as riding in daytime.

Insurance proved a lot cheaper too. It comes in around $500 for all-in, which is about half the price of the KLR for comparable coverage.

My bro and I pick up the bike on Wednesday--can't wait to really ride it!

Fantastic short film about guys committed to building bikes. Watch it. Maybe I'll keep my KLR after all!

Fat tire fun in the snow

I finally got a chance to trail ride on one of the new fat-tire trail bikes, thanks to my buddy Phil who bought one last fall (his is similar to the one in the pic). We took off onto our Almonte Riverside Trail this afternoon in the midst of snow squalls and biting wind, over a mostly packed snow surface hiding postholes and icy stretches. Phil gamely rode his 26" dually with studded tires while I practically cruised along on 5 psi balloons.
























If you haven't tried one of these bikes, I highly recommend it. The contact patch has to be around 48 sq in, which means you can float over almost anything like you're on suspension and find traction in the most ridiculous circumstances. For instance, this was the first time I'd ever managed to pull a burnout on a bike. I just pedaled like mad in circle on undisturbed snow, and carved an awesome lazy donut--complete with roost. Serious giggle factor. No motor needed for this kind of hooliganism.

The trail has some steep twisty sections that were completely eaten up by this thing. Cornering was a little weird at first, but once you get used to the side-slip you look for little berms to bounce off of and trust that the massive contact patch with its little knobs will snuffle out and engulf any tiny features offering traction under the snow. It was almost as easy as riding in the summer.

A bike like this opens up a whole new season for knobby fun when skiing conditions suck, there's not enough snow for snowshoeing and too much for trail running, and you don't want to take a bike on the roads because of the salt. Definitely on my list for next bike to buy.

Update: Rode the same sections on 26" duallie today with tires at 25 psi. Snow was hard frozen so it was surprisingly good to ride. Managed to do almost everything without dabbing, but icy sections were sudden death because I didn't have studs.

Edit: Contact patch size.

Jet engine project - Part 3


After spending several nights experimenting with some ghetto homemade tooling to bore out my replacement main journal bearing, I couldn't rig something that gave a smooth enough surface over the length of the bore. So reluctantly, I took it to a reputable machine shop to see if they could complete this step for me. Surprisingly, they fared no better despite three hours of trying. Worse, now the bore hole is about 0.001" larger than I'd like and a bit rough. Can't fix that! What a bummer, because I'd managed to machine the outside to within 0.0002" of the original part.

So much for "saving money"... now I'll just buy the tooling myself and have another go. That means making a new bearing from scratch. However, this time I'll start with the borehole and work to the outside. There's still the question of how to accurately mill the end cutout without a milling machine. I may be able to do that on my drill press--slowly. It's only brass, after all. None of this stuff would be a challenge on a CNC lathe but it's surprisingly tricky to do on a manual lathe. I've even tried maple jigs for offset turning the end mill. I could machine the maple to within a few ten thou of runout, but just could not get a decent interrupted cut in the brass with my makeshift tooling.

KLR 650 for sale

Yep, I've finally decided that this most excellent steed needs a new home. Bombproof reliability and rugged good looks aside, something smaller is probably better suited to the type of riding I would like to do now.

2000 KLR650
40,780 kms
$2500 safetied

- Doohickey replaced with Eagle Mike (don't believe the BS: my original chain tensioner was broken, as were those in two other KLRs I've inspected and fixed.)
- Progressive fork springs
- Braided stainless front brake line
- Upgraded subframe bolts
- New maintenance-free battery
- IMS foot pegs
- Moose aluminum skidplate
- Water pump seals replaced
- Maier handguards

When I first bought the bike at around 25,000km, I replaced all the wheel and suspension bearings with better parts, replaced the chain and sprockets, and generally tuned it up. I also inspected the clutch and valve shims not long ago, and both were in spec. Bike runs like a champ and pulls strong. I'll include the original fork springs, skid plate, and a smaller sprocket. Maybe some other odds and ends as well. If you've ready my blog you know what this bike looks like and can do, and it's never let me down.

Edit: Just to sweeten the deal, I have now installed a new Moose front rotor and new Galfer brake pads (green on front, black on rear). I've also disassembled and cleaned the calipers, changed the brake fluid, changed fork oil, changed engine oil, and cleaned and oiled the air filter. Bike is in heated storage and ready to ride.

Ontario invests in motorcycle tourism

Nice to see news like this for a change! Especially since it's right in my backyard.
