I just received these for my street setup. Warp 9 2.15 x 19 front and 3.5 x 17 rear. Not really Motard but should be good for the street. Running 100/90 and 130/80 Pirelli Scorpion Trails for tires. I have had pretty good luck with these and I like the way they ride.

Those look great! I'm anxious to see how they look on the bike, and to hear how they handle. I went with a slightly wider setup, but often wonder how the narrower set would handle.

Anyone else with 19 front/ 17 rear tires? I have a stock DR and am finding it that I like riding curves and accelerating, but also don't want to compromise stability. Anyone with 17 front/ 17 rear disagree that smaller wheel takes away stability, especially on highway speeds?

It depends if you are smarter than your bike, lol. Adjustments can negate the difference in handling, as does tire type and size, where your axle is in the rear (longer wheelbase or shorter), etc etc. I'm the only guy on this forum with my set-up, :rofl: so probably I'm the only guy here that can tell you if it can be stable or not. :pardon: (mine.)

"It is". Ex: A 19" Shinko 110/19 is 26" tall. My 17" P' Scorpion Trail is 26" tall. Tire selection/rim width, yada yada, will make or break the works. The axle is the same distance from the ground so tire cross section/profile will determine how it's behavior is for turning. A low sidewall 17" (70 series typically, 3.50" rim)) is drastically different up front so more needs to be done to make me happy for high speeds. I do a LOT of high speeds since I hang with a Beemer ADV'er often in the mountains. My street set-up is more "Scrambler" than true trail, but wth, I'm mostly on rough-ish
curvy county roads with a 40 mile high speed slab ride home. I may get ten miles of single track trail in for the day, but I'm not going to sacrifice such an awesome road ride for such a short single track run.

I can deal with it ok. I don't do much dirt or gravel roads, just single track if I'm off of a county road.
If a bike turns nice, and STAYS steady in a turn w/o standing up when you relax inside bar pressure, or fall in at an outer relax .. .. I consider that a nice trait. Rock steady at a ton, no twitching going off/on the power in wider turns, blah blah blah. . .= :2_thumbsup:

Were I a 60/40 rider, lots of dirt trail, I'd be 21". Average Joe DR: 19". I don't recommend a 17" up front if you are less than 98/2. My ring-ding is retired to the shed and I'm now a mellow wussy dirty bike has-been. My speech here only addresses your "stability" question.

Hi Locknut,

Thank you for replying with such detail and a nice picture of your bike. It really looks nice! :2_thumbsup:

Yesterday I went through some threads where people were discussing rim sizes and tire sizes, and thought that 19" front would probably work better for me. Now it's just a matter of finding a good deal on rims.

However, not trying to go too off topic, but did you do any adjustments to the stock suspension to make the bike more nimble on curves and tight turns?

I never really owned a different bike so this suspension is the only one i tried. The only thing i did was adjust the pre-load on the shock (I'm ~205lbs without gear, and being 6'4" the height of the seat is no issue), but people extensively bash the suspension as being too soft and unpredictable. I can understand unpredictability when it comes to off road, but do people usually change much for supermoto? Is putting thicker oil in the front and adjusting the number of clicks on the shock to make it somewhat stiffer a decent option? I'm only asking because if general advice is "get better front shocks to not be disappointed, might as well buy shocks from different bike that will fit a different dimension rim" then i will look into that route. Although from all I've read so far it seems that progressive springs upfront are a huge improvement on front shocks, especially when not much dirt riding is happening...

If staying mostly street or mellow trail, stock suspension can be ok with just some minor tweaks. Not so when in a hurry off road, especially considering your size, but we have to be realistic about our needs, desires, skill level, or whether we even give a damn, lol. I've made no adjustments trying to be more 'nimble.' I've done things for stability, but that's not the same thing.

A lot of us older guys here grew up riding monster power 500cc class 2 strokers with suspension considered a bad joke today, so we have different skill sets than the younger guys. “Tolerable handling” to me has made some younger guys come off the same bike cussing and swearing that Satan Himself made both the suspension and the exploding power band. That said, the best thing I hit on for bettering my DR 'sumo was the wider rough road forgiving tires (tall walls) and the Superbrace. I tried it all, and the biggest bang was those two, hands down. Did lots more stuff, but for staying in control on nasty curvy roads those two are big deals. Refinement was drop-in valving and a Scotts.

I've mentioned it before and it deserves repeating: The more basic and crude the suspension is, the taller the tire sidewalls should be. Applies to cars and trucks too. :2_thumbsup:

I'm a disciple of Locknut and will eventually post details regarding my CatSquasher front end setup in my build thread.

Basically, with Locknut's help and advice I ended up running a 120/90-17 Shinko 705 on my Warp9 supermoto setup. I have a 150/60-17 rear.

I don't do any dirt riding at all, but I wouldn't hesitate to do so if I had the chance. My only impediment is that my rear tire is a dedicated Bridgestone Battlax street tire, so going offroad would not be very recreational for me. Certain conditions would be perfectly doable, but if things got hairy I'd be screwed.

I am completely in love with my 120/90-17 front end setup. The only thing I feel I am giving up to a full-on supermoto setup is that the steering is not as nimble and the tire weight is a bit more than a 120/70 or 120/60 size. Otherwise, it's very stable whether leaned over or going straight.

Locknut is running a 2.50 x 17 front rim, I'm running a 3.50 x 17 front rim. His width is more appropriate for a 120/90 tire, but I'm perfectly content with my profile, which is squarer than his. I'd have to really, really push my cornering limits not to be satisfied with my tire profile. Given that I have such tall sidewalls, my tire diameter is only about 1/2" less in diameter than a 110/80-19 setup. According to Locknut the difference is negligible. But, the 120 tire and the 90 aspect ratio probably give a much nicer ride (can only conjecture, as I've never ridden a 19" front).

If I had to do it over again and were budget limited I would keep the stock 17" rear and simply get a 2.50 x 17 rim and spokes, front. Warp9 carries such a rim for the rear of the KLR and can probably supply the proper spokes. Procycle carries that size Excel rim with spokes for $319 to your door.
