G'day all - Wondering what tyres people are using for racing? Tracking my SMR511 yet the 4.25 inch rear limits choices and the majority of motard slicks here in Oz are a 165 rear. Was thinking I could stretch to a 160 (up from 150) rear without too much issues but don't really want to go to the trouble of getting a larger rear rim to fit the larger rear tyres. Any advice would be greatly appreciated.
Get in touch with Jovian Haidle from Jose Moto he will sort you out with some Goldspeeds. Pretty awesome SM tyres most of us guys in WA are running them.
I have a 160 on my 5" rim it is about half bees d!ck from my chain with no evidence of rubbing. I'm sure Jovian will have a super sticky tyre for ya.
You will actually have a smaller contact patch with the road by going to a 160 on a 4.25 rim plus you won't get to the edge of the tyre due to the pinched 160 being more curved. Tried it on my Husaberg SM and I couldn't notice much difference apart from being left with chicken strips, the pegs would hit the ground before getting to the edge of the tread. Stick with a 150 or get a 5" rim.
That's what I thought. I would prefer to stay with the stock rim and run a 150 but I can't find a super motard spec slick in that size
The goldspeed ultra street 160 rears are very skinny and IMO are a better fit on a 4.25" rim than the 5" rim I have on right now. The slicks on the other hand are a wider 160 more suited to 5" rims.
I run the Goldspeed street ultras on my 5" rim. With out off setting the hoop a little anything wider would rub on the chain.
You won't find slicks for the 4.25" as racing slicks come in proper 165/170 widths designed for 5-5.5" rims. You can run the road legal Goldspeed Cut slicks as they're not so bad on a 4.25" rim but not ideal.
