do you know about bridgestone s20 evo? i like bridgestone brand.
That's it. I generally adjust suspension between sessions after I get a chance to look at the tires, so a little loss of ease of access was an OK trade. The hose routed fine, so that wasn't an issue either.Maybe to keep it protected in the case of a slide?
Stock 140.What size did you go with in the Pirellis? If you went with a 150 size that would explain the slower turn in and then quick dip, once turned in. The tire might have more of a square shape because of our small (4") rim. I know many of the RC390 track and race riders talked about switching to a 140 from the 150 that comes stock on the KTM for the faster turn in.
Should have said "Just ANNOUNCED". Won't be available until early 2016.
Are there any issues with going to a 150 on the R3?Should have said "Just ANNOUNCED". Won't be available until early 2016.
As 87112's link to SportRider article states, there is no 140 size available, at least at first, so you'd have to go +1 on the rear and get a 150/60-17.
Can of worms time!Are there any issues with going to a 150 on the R3?
Thanks Fang for your indepth answer. You've convinced me to stay with the 140. I'll probably stay with the stocks for a little longer and see what is offered next spring or summer.Can of worms time!
1.) The 150/60-17 is .63"/16mm shorter, which means the rear of the bike will be 8mm lower and that's enough to make a big difference in handling characteristics.
2.) The 150 is .4"/10mm wider but there won't be a clearance problem.
3.) The 150 has a shorter sidewall by .32"/8mm, which means a stiffer carcass and harsher ride.
3.) The 150 circumference is 2"/50mm less, that throws off your speedometer reading very slightly (1-2 mph at 40-80mph) and increases wear due to more revolutions per mile (837 for the 150 vs. 816 for the 140)
4.) The overall shape of the tire will change slightly, which can adversely affect handling:
Here's the comparison:
Personally, I'd wait for them to come out with the 140/70-17 tire or just buy some S-20 EVOS in the stock sizes. There are really no benefits, and possibly a big down side in handling characteristics, to changing tire sizes on the R3.
