a female co worker of mine is wanting to buy her 18 year old non working son a yzf 250 that has been raced.the price is cheap, (anyone else hear alarm bells ) ? i have tryed to explain to her the cost of up keep on the four strokes and the amount of upkeep the bike is gonna require. i know her son is gonna ride the wheels off of it and hes clueless on upkeep. i wanna see the boy ride and have fun, but i know his mothers financial situation. ive tryed to convince them to buy a two stroke till the boy can get some knowledge of maintaning a bike, and hopefully get an idea of the cost of keeping one up. i know how advanced the thumpers are and im clueless on helping them keep it going myself.she thinks im pullin her leg on the cost of upkeep.. again, i know hes gonna ride it to death with no care..... your opinions count and are needed... thanks !!
