What "low priced" modifications are necessary for superior trail use-never on pavement?

Larger foot pegs

Something other than the stock front tire. You will have to do some research, Tracy and I both use the Maxis, but it seems the particular model has been discontinued. The stock front tire 'washes out' easily.. If you are on the taller side, and/or annoyed by vibration, an alloy handlebar (taller) may make an off-road adventure more fun (comfortable). A seatpad for anyone with an older 'butt'. Many have found comfort with the Sterns seat pad. I am happy, but spent alot more when buying the Airhawk. Have fun, Gerrry

If speed is no concern you could go one smaller on the front sprocket or a few larger on the rear.
