15/42 will give you 111mph (179kmh) @ 12,000rpm
14/40 will give you 109mph (175kmh) @ 12,000rpm
14/42 will give you 103mph (167kmh) @ 12,000rpm
No reason to keep it bone stock! Wire splice it (and preferably drill 2 x 20mm holes in the airbox lid) and release 50% more power!
I currently run 15/40 with an HRC transmission with a long 1st gear, but 14/40 is still fairly lively. Funniest was 16/38 which gives me a theoretical top speed of almost 142mph! 1st gear is a chuckle round town and away from traffic lights as it will do 67mph!
I think StephenRC45 tried 16/35 on his MC21F3 once for a laugh!
