hey fellas,
im restoring a nsr125r and want to give it a bit of extra go.

does anyone have a link of anywhere to get the Polini 153/160 cylinder kit.

I read on another thread the nsr150 tyga pipe can be used with a bit of work to the mounting points . is this correct?

any other tips.
I want to driveable just a bit more go so it doesn't feel dead after owning a tzr250 for my last bike 😅

Cheers lads
Chris

As far as I looked I never came across a polini cylinder kit, best chance you have is to look for a malossi 180cc cylinder kit.
You can find it on following link although they wrote 190cc it’s a 180cc

the best is to re-bore with a fresh nikasil and new piston & rings . you've got in UK plenty compagnies who do that for a cheaper price of malossi or else . it can be re-bore 0.50 or 1.0 and i suggest to fit that with a forged piston as Woëssner (piston kit ~£100)
