Renthal 91-95 Honda CRM250 UltraLight Rear Sprocket, 520 Chain, 44-Tooth Hard Anodized

Renthal UltraLight Rear Chainwheels are CNC machined from 7075 T6 aluminum to extremely tight tolerances, 66% lighter than steel. Computer engineered and tested to ensure a precise fitment, concentricity and load dispersion with tooth profiling to provide maximum power transfer. A combination of high strength base material, cutting edge manufacturing methods and exceptional hardwearing surface treatments its clear to see why Renthal's light weight all aluminum rear sprockets can be found on the rear wheels of many factory race team machines.

The Renthal UltraLight Rear Chainwheel is designed for 1991-1995 Honda CRM250 applications requiring precise fitment and dependable power transfer. This limited-edition rear sprocket uses a 44-tooth profile for a 520 chain and is manufactured from high-strength 7075-T6 aluminum. Its lightweight construction helps reduce unsprung and rotating weight compared with conventional steel sprockets, supporting responsive handling and efficient acceleration.

Renthal computer-engineers and tests each chainwheel to maintain accurate concentricity, load dispersion, and tooth profiling. The result is a rear sprocket engineered to transfer power smoothly while maintaining reliable chain engagement. A hard-anodized surface treatment improves resistance to wear and helps protect the aluminum base material during demanding powersports use. The precision-machined design is suitable for riders who want race-inspired performance without sacrificing fitment accuracy.
