Ok so i have a stock. Have had it for 3 weeks now. By this time next year i would want to get a mod trials bike. Would this cost alot of money to do and should i just stick with a stock trials. I really like mods better. But i mean it would be alot cheaper if i just stuck with a stock. I am pretty short for my age. I am 13 and like about 5 foot 2. It would probably be easier if i got a smaller bike cause it would be easier for me to whip around. Would this be a good idea, is it hard to go from a stock to a mod. Thanks.
