Honda motorcycle owners with XR600R, XR500R, XL250, XL500S, or similar models from the 80s and 90s, this NICHE front sprocket is a quality replacement for your worn-out original! The 14-tooth design with 520 pitch matches OEM specifications perfectly, and it's made from SAE 1023 structural carbon steel that's been sandblasted and electrophoresised for durability and corrosion resistance. The hub has a 22mm inner diameter with a second 25mm ID section, and the mounting holes are spaced 42mm apart - all precise measurements for proper fitment. Replaces Honda part number 23801-MK2-010 and works with JT Sprocket models too. Compatible with 1985-1990 XR600R, 1979-1980 XR500, 1981-1985 XR500R, 1982-1983 XL250, 1979-1981 XL500S, and several CB250/CL250 models. When your sprocket teeth start looking sharp and hooked instead of flat or domed, it's definitely time for replacement to prevent chain slippage and poor performance. This NICHE sprocket delivers solid quality at a reasonable price, with proper heat treatment and finishing that should last through plenty of riding. If you're doing chain and sprocket maintenance on your vintage Honda, this front sprocket will get your bike shifting smoothly and transmitting power efficiently again.
