How does adding flywheel weight work on 125s and minis?
It works great for woods riding and for timid, less aggressive riders. We sell tons of flywheels for minis because it is the best, most cost effective way to make the motocross type power usable and controllable for kids, beginners, and slower riding. A fast and skilled MX rider probably would not want to add much flywheel to his small engine, but there are exceptions. Andrew Short used a Steahly Flywheel on his RM 125 to win the East/West Supercross because his engine was so highly modified it need more flywheel to get the power to the ground. When choosing the amount of weight to add to a small engine use caution. It is possible to add too much, causing the bike to bog instead of accelerate when slipping the clutch to get it into the power band. This is usually not an issue with timid riders because they don’t slip the clutch, so they can get the heaviest weights (10 to 12 ounces). A fast and aggressive rider should get the lighter weight flywheels (6 to 8 ounces).
