light and durable.
OEM part was on backorder. Which ended up being a good thing. I had originally tried to order a Renthal, but couldn't find it on your website. Made a phone call and your staff found it for me. You guys are great !!!
great replacement for oem sprocket, can't go wrong with Renthal products
Great long lasting product!!!
My front sprocket got worn down like any old bike, so I simply bought this one based on reviews. And it's good!!
This sprocket works great and it was an easy install
Renthal makes proven durable products. Have not had a Renthal sprocket fail on me. Like any front sprocket, they are steel and offered in an array of sizes to fit your gearing needs.
Only trust Renthal!! Don't put that cheap stuff on your bike, you'll be replacing cases if you do!
It was a great replacement for the factory 13 tooth that had 3 teeth broken.
awesome tech help, price, delivery and service. I have not yet installed but Motosport customer service is always great.
Best sprockets out.
Very durable, good quality sprocket.
Durable,holds up well on my 2 and 4 strokes. Great buy.
Since I'm converting my 450R to a more desert/trail friendly machine one of the first changes I made was a gearing change. Going up 1 tooth on the front as apposed to several teeth in the rear made sense since the bikes stock gearing is setup for MX, which is way too close for trails or desert.
The one tooth change in the front is fairly substantial. It is similar to making a 4 tooth change to the rear. The bike still pulls all 1st-5th gears without a problem. Top speed is higher which helps for valley crossing and 1st gear remains usable for extremely steep technical hill climbs. On my last trail ride I handled most hills in 2nd without having to downshift or bogging down in 2nd. 1st gear would be suited for National Hare and Hound 2nd loop uphills.
Overall, it is a 5 star sprocket. It took about 5 minutes to install (I'm very mechanically inclined so may take others longer). Went on easy, perfect fitment, and didn't have to remove the chain. It is a good looking part, well machined. Packaging is very nice. Very durable and performs excellent. I definitely recommend this product.
Very durable and easy install
Got to my house quickly and went on the bike easily. Renthal makes great sprockets.
I got this several months ago in order to gear my 2002 YZ85 down a few teeth, and it has been great. It was also very easy to install (I've had it on and off a few times now).
Definitely makes a difference when trail riding. Used to bog a little going up hills and had to downshift to make it up steeper hills and no longer have to do that. It made my Honda CFR250L feel more like a true dirt bike than the stock gearing with this simple modification. Did decrease top speed a bit on this dual sport bike but still can easily cruise at 70 m.p.h. on the pavement when needed. Cheap, easy modification with definite benefits you can feel.

Something else you may want to check before changing gearing is the chain tension. You say the bike jerks when she gets on the gas, that is usually a sign of a loose or stretched chain. Be sure to adjust this to the manufacturer recommendation with is usually about 1" to 1 1/4" of free play.
As a general rule of thumb to get more acceleration (less top speed), you will want to either drop teeth in the front or add to the rear sprocket.
To increase top speed, you do the opposite.
It is impossible to get both more torque AND more top end with sprocket changes. The only way to accomplish this is to change the bikes transmission gearing (1st gear ratio, 2nd gear ratio, and so on) and even with this you could only accomplish more torque on the bottom and more top end in the higher gears.
It is a give and take. With sprockets if you want more torque you sacrifice top end. If you want more top end you sacrifice torque.
I hope this helps.
