The SUPERSPROX Countershaft Sprocket is an 18-tooth sprocket designed for selected Triumph motorcycles. It is made from SCM-435 carbon-free steel and features an impregnated construction intended to help prevent breaking and extend sprocket life. The sprocket has an ultra-hard surface layer measuring 0.5 mm that reduces friction and helps prevent power loss caused by chain drag.
Fully lightened with radial holes, this sprocket is intended for off-road and street applications. Grooved teeth support fast dirt removal in off-road use and reflect the specification of SUPERSPROX factory racing parts. The distributor part number is CST-1183-18-2, and the manufacturer part number is CST-1183-18-2.
Vehicle fitment includes the 2004 and 2015 Triumph Bonneville T100; 2007, 2009, 2011, and 2016 Triumph Bonneville 865; 2009 and 2010 Triumph 865 Speedmaster; 2012 Triumph Scrambler 865; and 2005 Triumph Thruxton 900.
