Key Features:

  • 42-tooth rear sprocket for optimized acceleration and drive ratio tuning

  • Hard anodized finish for enhanced corrosion resistance and long service life

The VTX aluminum rear sprocket is an ideal choice for anyone looking to reduce drivetrain weight, fine-tune gearing, or replace a worn OEM sprocket with a higher-quality component.

Great ordering experience

Service and support were great, order arrived quickly and in good shape.

It's the information I needed for my boat motor. The only issue I had with this maintenance manual was the way the manual was finished. I've worked the the graphic arts industry for 50 years and am well versed in print finishing. The book will no doubt stay together, however there is excessive glue on the spine as the cover wraps around the front/back that distracts from the overall appearance.

Great prices and a surprisingly fast delivery, which despite choosing the most economic choice (2-14 days), I received the items in 5 days - saved more than half in shipping. Great all around experience and great product extremely well packaged. Thank you, folks!

Quick ship. Thanx
