No more loose bolts on that XL, Big Twin or Tube Frame Buell motorcycle – not with our Hugh’s HandBuilt HD Sprocket Lock System.

Designed to work on ALL XL, Big Twin and Buell Motorcycles that use a 5 bolt pattern on the rear sprocket. This system is 100% Bolt On and creates a positive retention on the sprocket bolts, ensuring that they cannot back out or come loose again.

If you’ve ever witnessed the damage, frustration and downtime that a loose sprocket creates, then you’ll understand why we’ve created this solution.

The 5 Bolt pattern used on modern HD motorcycles has been around for a long time, while the bikes have gotten heavier, more powerful, have better brakes, and come with much better tires – and all this creates a nice reason for those bolts to work loose.  If your bike has an *HD style rear wheel, and uses hardware with a 5/8″ Hex Head, then this is for you!

“Hey Hugh, will this fit my XXX Blah Blah whatever model custom with a chrome fender and a Slayer sticker on the tank?”

“If you can slip a 1/8″ bit of steel between your sprocket bolt heads and whatever else may be close to them, then yes…” – the low profile design should fit any and all customs and OEM bikes using an HD Style Wheel.

Save the frustration and downtime – this system installs with basic handtools and just a bit of time on your part…  Easy stuff, and it looks killer!

*The only current exception is wheels that aren’t threaded, but use a flange/bolt/nut system instead – and while this will still fit, it doesn’t lock the nuts into place on the backside, we have a solution coming for that VERY soon – don’t fret!

*please note each unit can take up to 14 days for delivery
