Was a little sceptical adding a flywheel weight

Comments On Jul 21, 2015:Quite happy with the 9 0z. flywheel weight. It makes the bike fire up easier. The added weight has a little pulsing feeling just off idle but does allow the bike to chug at the lower RPM's better. I do not feel any less acceleration with the weight. In fact it seems to actually put more power to the ground than stock. Happy with the weight. With Pipe, silencer, jetting and the FW weight in really has made the YZ come alive and be a far better bike with the mod's. I was far to tame in OEM configuration.

As Advertised

Comments On Jun 05, 2015:I don't usually leave reviews but I am really impressed with this product. KX450s aren't really built for trail/single track riding, but this flywheel weight has helped my bike lug so much better in tight areas! It lets me roll over stuff and last time I was out on the single track in the mountains I had wayyyy less stalls than I had before. This was a lot cheaper option than switching to a KTM 300 which is what I was thinking of doing before I put this part on.

Easy install and perfect fit

Comments On May 14, 2015:It fits perfectly and was way easy to install. I liked how it had several fails safes so if installed correctly there is no way it can spin off. The bike seems to resist stalling at low speeds and even idles smoother. After installing it smoothed out the climb into the higher rpms. I don't get in nearly as many fights with loose gravel roads as I used to.

Better off replacing whole flywheel

Comments On Mar 22, 2015:I love Steahly products, but I am not really happy with the flywheel weight for the CRF150r. Everything I read said to be very careful that the bolts are tight and to use threadlock and then use a cold chisel to pinch the threads. After doing all of that, it still worked itself loose in about 5 hours. (The bike was making a noise that sounded like piston slap, but then I realized it was coming from the bottom end.) I pulled it out and re-tightened it, but if the problem occurs again, I will replace the whole flywheel with a complete flywheel. (I believe Trail Tech makes one.) Its simply too risky to have a flywheel weight that comes loose, and I really don't want to have to remember to pull the side case off every 5 hours to check it.

Great Training Aid

Comments On Mar 15, 2015:I put this on my son's KTM 85SX 2-stroke, and it really made a great training aid. It makes it easier for him to quick start without stalling, keeps the motor smooth at low rpm's, and generally makes for a more fun ride.

Excellent Product - 350 XCF 2014

Comments On Mar 16, 2015:I usually to not rate most of the products but this one I had to give a 5 stars. It did change complete the baki and made it much more useful. Before it I had some difficults to handle the bike in a tight single track. Now it runs smooth with low RPM... really great product.. I would recommend for 350 XCF owners.
