hello I am very interested in buying a Yamaha 125 xvs, I have been to a few motorbike shops to try out the size of the bike, but have only sat on the 125 intruder and honda shadow I prefer the look of the xvs but am worried im too big, I have 6 foot 3 and 15.5 stone, will this size bike be okay or will my knees be hitting my chin?
