Heat treated and hand finished to perfection, all JT Sprockets meet or exceed the highest possible quality standards for the powersports industry. Each sprocket goes through 10 quality control checks before it leaves the factory. Review: Good quality and fit great - I used the sprocket to replace the 50 tooth OEM one on my TW 200. Now the bike doesn’t rev so high when going 50 to 55 miles an hour down the road. Still has plenty of low end torque since first gear is so low. Perfect upgrade for this Bike. Review: Works great for a 350lb TW200 rider - Super easy to install on my 2024 Yamaha TW200. I'm 350 lbs, and the bike shifts easier in city traffic, and can reach top speed without screaming as much. I took my wife on a ride (about 475 lbs total) and the bike topped out at about 55 mph in 4th gear - 5th gear was too much with all that weight. Alone I can ride at 65 in 5th gear and RPM's aren't screaming - they're right in the power band. Great price, and great durability/build quality for the money. Would definitely recommend for city/backroad riders. Offroad, maybe not so much. With this gearing and my heavy 350lb butt, Each gear covers about 10mph. Ie., shift from 1 to 2 at 10mph, shift from 2 to 3 at 20mph, shift from 3 to 4 at around 35 mph, and shift from 4 to 5 at around 45-50 mph. ## Features - Made from C49 high carbon steel - Heat treated and hand finished to meet or exceed OEM standards - Outlasts any mild steel or surface hardened sprocket - 45 teeth steel sprocket - Fit type: Vehicle Specific ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B001AVW0B0 | | Best Sellers Rank | #391,674 in Automotive ( See Top 100 in Automotive ) #413 in Powersports Sprockets | | Brand | JT | | Customer Reviews | 4.4 4.4 out of 5 stars (63) | | Date First Available | January 30, 2007 | | Exterior | Painted | | Is Discontinued By Manufacturer | No | | Item Weight | 1.69 pounds | | Item model number | JTR1842.45 | | Manufacturer | JT Sprockets | | Manufacturer Part Number | JTR1842.45 | | Model | JTR1842.45 | | Product Dimensions | 7.9 x 7.3 x 5 inches | ## Images ![JT Sprockets JTR1842.45 45T Steel Rear Sprocket - Image 1](https://m.media-amazon.com/images/I/81mamumEsGL.jpg) ![JT Sprockets JTR1842.45 45T Steel Rear Sprocket - Image 2](https://m.media-amazon.com/images/I/51M3m6IrsPL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good quality and fit great *by N***N on July 29, 2024* I used the sprocket to replace the 50 tooth OEM one on my TW 200.
