Quick acceleration chain and sprocket kit 15/48
Chain was 3 links shorter than factory chain and about half as thick but still fit very nicely, gold color looks awesome and is very light weight. Easy to install with chain riveting tool I had, replacing both sprockets and chain install took about 45 min with cleaning. Drive sprocket looks sturdy and fit my 05 yzf r6 perfectly. Rear sprocket looks good wish it was a little thicker/ heavy duty but keep in mind you loose half the weight of the factory parts I haven’t gotten to ride it after the install I was missing the drive sprocket nut and washer but on looks alone this kit is worth the money for sure I can’t wait to test it out.
