Title: Options for narrower/slick tyres for racing
Post by: evtricity on November 27, 2015, 04:45:53 AM

I've been racing my SR for a while and have been thinking about running a set of Pirelli Diablo slick tyres. I currently run Dunlop Alpha 13 in 110 F and 140 R.

Unfortunately there seems to be no manufacturer who makes slick tyres in the stock sizes - 110 front and 140 rear.

Pirelli produce a 100 70 17 front and 125 70 17 rear which would fit well on the Zero's relatively narrow 3" and 3.5" rims. This might put more wear on the rear tyre with the SR's high torque but I believe the improved handling (easier turn in) would be worth it. I've read of Ninja 250/300 riders using them and their bike weights are comparable to the Zero.

Has anyone run slicks on their Zero or have run narrower slicks on a gas bike? Any other tyre options I could consider?

An update on my search for track tyres for a Zero SR ...

In 2015 Pirelli released a Supercorsa SC rear tyre in 140/70 17 SC2 which can be paired with their existing 110/70 17 SC1 tyre. Previously only a 150/60 was available which is a stretch on the Zero's narrow 3.5" rear rims and the extra width comes very close to touching the belt/chain.

I have this picked up this 140/110 combo and will try them on the track and provide an update here. I think these should be the best track tyres available in the stock sizes (110F, 140R). They are also DOT approved so can be ridden on the street as well.
