The CRF ignition is what you really want and need..The stock 450R flywheel is a 26oz and the stock CRF is a 14oz..HUGE difference. Trail Tech sells the cheapest version and lets you choose between a 14, 17, or 20 oz flywheel. I wouldnt buy a revbox or just a flywheel, you gotta do the igntion to reap the benefits.
