hey yall! i have a 1998 kdx 220 and im 14years old so i dont have alot of money to spend on my bike. right now i have 80.00 dolars and i was going to spend it on a maier mx rear fender a new front fender and a new side panel becuse mine is scratched up badly. but my friend told me about this trail tech electronic speedometer that is also 80.00 and i dont know what to buy. what would be a better investment?
