Built from hardened steel, the 65-tooth design provides reliable engagement with the chain while the precise bolt pattern and center bore match common Coleman, Baja, Hensim and TrailMaster mini bike and go‑kart models. The package includes one sprocket and five master links so you can swap it in and get back on the trail quickly.\u003c\/p\u003e\n\n\u003ch3\u003eWill this sprocket fit my mini bike or go‑kart?\u003c\/h3\u003e\n\u003cp\u003eMeasure the bolt circle and center bore to confirm fitment: this JINGKE sprocket has a 50.5 mm bolt circle diameter and a 37 mm center hole.

The JINGKE 65-tooth rear sprocket suits owners of 97–100cc mini bikes, go-karts and drift trikes who need a robust replacement part that restores drivetrain reliability or changes gearing for stronger acceleration. Hobbyists, small vehicle repair shops and weekend riders who want a solid steel sprocket with clear fitment dimensions will find this part practical and cost-effective. If you’re unsure about compatibility, measure your current sprocket’s bolt circle and center bore or compare with the listed vehicle models before ordering.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Is this sprocket compatible with a #35 chain?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes.
