YZ450 Flywheel Weights?

17 posts in this topic

Yes!

It will help starting, and not stall as easy,.....keeps engine momentum going when climbilng hills, helps with slippery conditions, lets you control rear wheel spin better, eases the power delivery....

many pro riders use them...why not you too?

I just put a 9oz heavier flywheel from Steahly. It made a world of difference!!! the bottom end is really smoothed out and my stalling issues completely disapeared. It starts easier, it runs smoother, and even though some of the snappyness is gone, I am way faster in the woods. I give it a big double thumbs up.

I'm the odd man out on this one... I put a GYT-R heavy off-road flywheel weight in my 06 and while it did help maybe a little bit, it will still flame out in tight trails like nobody's business.

True, my bike will still stall easier than say, an off-road 450, or a 2-stroke.

But its still less stall-prone than stock.

Mine stalls WAY too easily, even with the heaviest option flywheel available from Yamaha. I think I have clutch issues... I'm going to try a different oil and inspect the clutch again and see if I can get to the source of the problem.

Get the heavy GYTR flywheel, it replaces the stock one.

With all parts check the TT store first, if they don't offer one then.

If you can't find the flywheel listed with the TT store email them. They've got GYTR parts before for me that weren't listed.

The Steahly flywheels for the '06+ bikes are a totally new replacement flywheel with the weight welded on.

For what it's worth... The Steahly and the GYTR Off-Road flywheel are EXACTLY the same. They even come in the same exact packaging. I'm thinking Steahly must make them for GYTR - however the GYTR is cheaper.

You haven't looked closely enough; Yamaha has two:

I have the 9.21 oz. GYT-R (GYT-2S297-50-50), and it's the flywheel the bike should have been built with. IMO, the lighter GYT-2S297-50-00 is a waste of time.

BTW, the pictures are of flywheels for the previous 450 models.

Here is the stock flywheel and the GYTR +9.21 oz offroad flywheel for the '08 and I would assume for all '06+ YZ450s

I'm looking for a heavier flywheel for my 2004 yz450f, that is not a bolt on. I can't find 1, does it exist? Gytr said they didn't carry it when I looked up my bike. Will the 13oz bolt on work just the same ???
