Anyone know what the caliper mounting centre and piston size is on the front of S1.
Is it not in the service manual?
Why’d you want to know?
Ian
Mounting centres are 130mm
Piston size on std front is I think 38.1mm
Thanks for that, i thought they must be about 130 ish.
There was a set of AP’s on Ebay from the rear of a Scooby 300x28 discs but the mounting holes are 180mm so way to big.
Glad i didnt buy them now.
They sold for �450 and had only done 700 miles.
