Motorcycle 15-24 Suzuki DR650S 644 1. parts that are used exclusively in competition on race only vehicles. These parts do not require approval as long as they "are not used on public highways". Labeling a product as being for "Racing Only" or "Closed Course Competition" is not sufficient for it to be included under this classification.
Looks and sounds great. Installed on a 2023 DR650. Took me maybe 20 minutes from start to finish. You will need a phillips screw driver and an allen wrench
