Steahly Yamaha YZ250/ 250X 03-20 11oz Flywheel Weight

YZ 250 Five Star Rating (their highest) in Motocross Action Magazine August 2011... "makes each gear pull further, stronger and longer". Make your power as smooth and tractable as Randy Hawkins YZ when he won the 2004 National Enduro Championship using a Steahly Flywheel. Reduce stalling like Jason Raines when he added a Steahly Flywheel for his 2003 and 2004 National Hare Scrambles Championships. Get predictable and reliable power like Barry Hawks GNCC Championship winning YZ 250. Easy installation, no special tools needed, but an E-3 engine lock up tool will make it easier. We recommend adding 11 ounces for most intermediate trail riders and less aggressive MX riders. 9 ounces for aggressive trail riders and intermediate MX riders. 13 ounces for casual trail riders or very technical terrain. 7 ounces for aggressive MX riders. Fits under the stock plastic ignition cover with out modification, however, if you have an after market metal cover such as Boyesen, you will need to get our Y-826 cover spacer.

• Flywheel weight includes stator cover spacer if required
• Increased flywheel mass/inertia provides smoother power
• Reduces the tendancy of the bike to stall at low RPMs
• Inertia increase allows for better traction on loose slippery terrain.
