flywheel weight?

[mad_biker]

I'm thinking of gettin a flywheel weight for my 05 yz125 and wondered what weight you guys would sugjest.I think they make 7, 9 ,and 11 ounce.Oh and I ride mostly in the blue ridge mountains.

I have a 11oz Steahly on my 01 KX250. I love the way it handles now. I would think a 9oz would be sufficient for a 125. They really help all around. It's like night and day riding my bike now. I ride trails alot, but have taken back to riding MX. Overall, my bike still has the snap when I want it, and keeps the power on the ground.

I know it doesn't apply to your '05, but it should give you an idea of what you'll need.

woah, awesome chart.

i have an 9 oz on my RM250, and it does just fine- i like it a ton better in the woods now with the weight- i am considering the next heaviest weight which is 11 oz, but i am way satisified with what i have now- especially when climbing a hill, i can tell a big difference- u won't have to fly up the hill anymore, although i still choose to- LOL

I think the chart says it all. The more weight, the smoother the power. The less weight, the less change you will notice in the power delivery.

I think I will go with the 9 oz one cuz I ride in a lot of trails and mud but don't want to loose too much acceleration because I ride some fast trails too. Thanks for yall's help

You won't lose any acceleration. It slows the revs a bit and puts more power to the ground versus just spinning the tire. It's still all there when you want it.

What does changing the flywheel weight do to your bike.

[souphmars]

lemme take a shot at this- if u add weight, it will make the engine rotate slower, and give it a added inertia- which makes it harder to stall it- it also decreases wheel spin, kind of makes it hook up better- u can also lug on it a bit more- some people say it adds bottom end, which is not true- it doesn't change the engine like that, or move any power- if u put a lighter flywheel on a bike all these things would change- if i am wrong other people on will correct me

When we started making flywheel weights in 1987 very few riders understood the benefits of adding flywheel weights. Since then the popularity of adding flywheel weights has increased dramatically. More and more riders discover that they can go faster for longer with the smooth power delivery, better traction, and reduced stalling that Steahly Flywheel Weights provide. Adding a flywheel weight will increase the rotating mass, or inertia, of the motor. The result is an engine that is a little slower to rev, has more controllable power delivery and less hard hitting power, a more usable low to mid-range, and is less likely to stall at slow speeds or with the rear brake. What you will feel is better traction when it is slippery or hard pack, a torquier and broader powerband, the top end power on many bikes will be improved with less tendency to lose RPM's when climbing or hitting obstacles. The easier to control power will help you conserve your strength and energy, plus many bikes start easier with the added weight. Most Steahly Flywheel Weights screw over top of the stock ignition flywheel using our exclusive patented mounting system. Most can be installed in less than a half hour without removing the stock flywheel from the engine. Our weights are also easily removed so you can change the power delivery back to stock for different riding conditions. Steahly Flywheel Weights are machined from solid steel billet on computer operated lathes for the ultimate in balance, trueness and strength. Our weights are designed to fit each specific model of motorcycle for a close fit and best possible performance. For most models we offer several different weights so you can choose the amount of weight to suit your riding style and conditions. Generally for a fast, aggressive rider or for faster terrain a light to medium flywheel weight would be the best choice. For a slower more casual rider or for riding slower technical terrain a heavier weight is ideal. Call us and we will be happy to discuss your situation and make suggestions. We also carry a wide range of other off road accessories, many of which are special or hard to find. All of us at Steahly Off Road are serious dirt riders and racers and the products we sell have been used and tested under real riding and racing conditions.

good post loki- what is said about climbing is way true- that is where i tell the biggest difference- ride a factory bike or something w/o a flywheel weight up a tall or long hill- then ride 1 w/ a flywheel weight, u can tell a major difference
