      When you’re looking for the benefits of a heavier flywheel but don’t want to replace the flywheel itself, pick up the Steahly Heavy Flywheel Weight for more momentum and faster riding right out of the gate.

      A heavier flywheel can make a big difference to the characteristics of your dirt bike’s engine. With heavier inertial mass your engine will have more spinning momentum. When you’re on the throttle this translates to the power building up and coming on more smoothly, giving you increased traction and less stalling at low rpms. These characteristics are perfect for new riders just learning throttle control and seasoned enduro riders that need the extra momentum and engine lugging ability when they run into slow, technical terrain.

      If you find yourself disliking the need to wind up your engine, install a Stealhy Heavy Flywheel Weight to put your bike’s power exactly where you want it.

    • Securely and easily attaches to existing flywheel
    • Comes with hardware and spacer plate
    • Makes for smoother delivery of power
    • Increases traction on difficult terrain
    • Reduces likelihood of stalling at low speeds and rpm

    You will be amazed.

    Comments On Jan 26, 2016:I ran one of these on a KX 250 2 stroke and a KTM 65SX. The results were calmed down power characteristics, enhanced traction, and a less tiring ride. Still has the same horsepower, but no longer light switch instantaneous. Without the weight, the front wheel of the KX would shoot up instantly. With it installed, the front wheel would shoot up slower and more controlled. Great for technical stuff and hill climbs were traction is key.

    Can't go wrong

    Comments On Jan 06, 2016:Aside from putting it on correctly, there isn't much that can go wrong. The weight does what it is supposed to do once attached. I would recommend!

    Two thumbs up

    Comments On Jan 01, 2016:Great product. Definitely helps with low speed stalls on tight technical trails. Install is a little tricky on KTM - be patient.

    High Quality

    Comments On Dec 17, 2015:Steahly makes some good stuff. Comes with everything you need. May want to get the engine lock up tool Tusk makes in addition to this, will make the installing easier.

    Labor intensive, but effective

    Comments On Dec 08, 2015:Bolt on weights are much easier to install, but with some time and patience, the glue/bake weights are still relatively easy. Great upgrade to a '13 KTM 450 to prevent stalling for in tighter singletrack

    Comments On Oct 14, 2015:I put this on my CR250 that i'm setting up for singletrack and the difference is better than expected. I went with 12oz. and Im glad i did. Stalling issues in tight rocky areas has gone away . My bike lugs along great at low speed and just feels all around better.

    Loved it

    Comments On Oct 13, 2015:Made a huge difference during low end operations. Kept the bike from stalling and let me "lug" the bike a little more when I needed it.

    Transformed my bike easier to ride tight sections

    Comments On Sep 28, 2015:Transformed my bike easier to ride tight sections. I was afraid the bike would feel slower after installation. That doesn't appear to be the case the bike still rev's up very fast. I think it has improved wheel spin somewhat when searching for traction in sandy conditions
    Pro's Easier to launch no longer have to rev the engine much on launch Doesn't flame out suddenly with no warning anymore when putting along or launching. More forgiving if riding a gear to high smoother when lugging motor.
    Cons Having to epoxy this to the flywheel meant no going back after installation (Very glad i liked it)
