CHAIN & SPROCKETS KIT
Kit Includes: Dirt Tricks countershaft and rear sprockets & RK MXZ5 Gold Non O-Ring Chain.
Rear Sprocket Features:
High quality heat-treated chrome-moly steel which is 2.5 times stronger than steel and 3 times stronger than 7075 alloy.
Closed Truss" design on sprockets evenly distributes stress levels allowing for an overall decrease in weight.
Front Sprocket Features:
Ultra-hard tool steel. Most front sprockets sold today are “case hardened”, meaning that only a thin outer layer is hardened, and below the outer layer is soft steel.
Sprockets are made in USA.
RK MXZ5 CHAIN:
RK’s NEW MXZ5 Racing chains are made for the serious supercross and motocross racer. MXZ5 chains feature chromoly steel construction with seamless rollers and bushing. RK’s reinforced Chromized pins drastically improve the wear resistance more than two times compared to normal non-sealed chains while absorbing shock loads from extreme jumps. All components are heat treated using RK’s exclusive HIT (Heat Induction Transfer) process. 520MXZ5 has a maximum tensile strength rated at 8,500 lbs. and is suitable for 125cc to 500cc class racing. MXZ5 has a higher tensile strength and higher rigidity than its predecessor MXZ4 chain.
