Me and Pete do spend alot of money but we are racing some big name bikes, like Rath, sparks, and so on most of them are not 450 more like 495 or 540 ect, with alot of money. most of the guys we race with are from NY and they travel to alot of big races. I don't really like to buy used parts so ill pay the price for new so I dont get f*cked on parts. For race gas it from 75$ to 140$ for 5gals. gas last summer was 97.9 to105.8 a liter and we travel up to 600k's to a race. and a other 600k's home. I pull a 8x16 enclosed trailer with 2 quads and parts to rebuild them at the track if needed to. alot of the of the money we spend is in traveling.
Yes you can buy used parts and save money and if the track is right by you, you save alot more money .
