Gear Up Kit 15/41 Press Pm Tuning 125-180cc 2T
£60.00
Pm tuning gear kit press fit. Meaning a 10 tonne press is needed to remove and refit the gear.
15/41 on 125 primaries is about the best all round gearbox in my opinion. Its a bit taller than 180 gearing. 12-13' wheels capable of 100mph easily with the right setup and tune. While 10' wheels tend to need more gearing, 180 primary with 15/41 secondary is my favourite.
