Time for a new chain and sprockets on your GSXR1000? This NICHE kit has everything you need. It includes a 17-tooth front sprocket, a 42-tooth rear sprocket, and a premium 530VM-X X-Ring chain that's 114 links long (you may need to cut it to fit). The X-Ring design offers great life and low friction. This kit fits 2009-2016 Suzuki GSXR1000 models, including the special editions. It replaces OEM numbers like 519-KCS1460K-K001. NICHE parts are known for being good quality replacements. Remember, always replace your chain and sprockets as a set, and have the chain installed/sized by a pro or someone who knows what they're doing – a broken chain is dangerous. A fresh kit will make your bike's power delivery smooth and crisp again.
