in september 2006 i bought my cpi gtr brand new i paid £2000 otr and lucky for me it had been fitted as standerd with a 100cc engine i dont now if you all know but they made 10 gtr bikes with this engine size so instead of the 50cc going between 30-45mph mine can go 125mph and the red line on the rev counter is at 15500 revs a minuit and ive had it at 18000 revs screaming the %!¤ out of it making it go 142mph!!!!!!!!!!!!!
