Derbi GPR50/75 tuning parts

Tony Sherriff /

Does anyone out there know of suppliers of performance parts for the Derbi GPR50 & 75 ? Cycle Imports of Florida seem to be the main one, but are there any others?

I would be particularly interested in a supplier for a race cylynder for the GPR 75. (the cylinder is apparently different to that of the GPR50 kit due to a different stroke on the GPR75 engine. Can anyone confirm this?)

Thanks, TONY.

Hi. look at a little bit of piston, i think it is the same as the 50 cc only the bore is 47 mm instead of 40mm but not 100% sure.
