So that's where my lawnmowers engine went! 
It's fine for what I need it for, at least for now. I can't get a higher engine bike until I am 20, stupid bike laws, but the top speed of this model is 82mph and there is no where I can legally ride over 70 and all the roads I will use daily are max 60.
It's really fuel efficient too!
That is a beautiful bike. How much are they asking for it?
£1,300 - only has 4000 miles on the clock
