  • Renthal Front Sprocket

    Renthal Front Sprocket

    Michael in NY

    Solid construction, you can feel the quality

    Installed a 13 tooth, down one from the stock 14 on a 2013 Honda TRX400X. I have 22" Maxis Razr II on the back, up 2" from the stock 20" tires. I did not feel that the 22" tires changed the low end a lot, but once I installed the 13 tooth front sprocket I really loved the way it rides now. I still have plenty of top end speed for tail riding in the NY & PA woods, but get there quicker. I use to feel I needed a 1.5 gear on some hills. Now 2nd is just right for hills and actually I feel I could get into 3rd more often. You can feel the quality of the Renthal sprocket in your hand over the original. I only have one year on the original, but I feel this one will outlast that for certain. The cost difference is negligible. As always Rocky Mountain was easy to work with prior to the sale, delivery was quick, price was right.

    ran this sprocket for nearly 25 hrs with absolutely no signs of wear up until I traded in the bike. Will be purchasing again for new bike.

    good wearing sprocket

    I did have an issue with this sprocket, it is too thick in order to use the lock collar in a positive latch but it has never came loose.
