1500 Prosport rear sprocket

[simon t]

Has anyone any data about rear sprocket sizes for a Prosport with a 1500 engine?

Would have thought would be same as 1300 unless it revs more or less that is.

More power means higher speeds quicker hence longer gearing ... well thats how my brain thinks

hi simon.
my dad has converted his 1300 to 1500 and after wondering why were sitting on the limiter for so long duncan williams told us that you have got to change the front sprocket to a 17 tooth because if you use the 16 tooth that radical put on the engine when the give it to you then you dont go much faster at all. since we have changed the front spocket the car is much better. hope this helps .

Thanks Kieran! Just spoken to Mark at Mansol and got one on the way. Are you guys doing the Radical Challenge this year?
