I wont bother with a tacho off of Ebay then !

I have geared mine up one tooth on the front sprocket and was surprised how revvy it still felt - CCM claim a top speed of 72mph - not for long I suspect as you say Jape ........!

Trouble is in the UK every "young mum " in a family car has 100HP+ and needs to be somewhere else in a hurry - does not make for pleasant riding with a car 5ft from your rear and the driver applying make up !!

I use the small roads where I can but that is not always possible in the crowded UK .

I dont think I will be revving even to max power ,8500, as it feels "enough" at 50 mph , was interested to check that it was a "standard" ratio - still 125 gearbox ratios I suspect .
