About Burly Brand

Burly Brand builds handlebars, suspension, seats and bolt-on kits aimed at the rider doing the work in their own garage. Its slammer and stiletto shock kits and bar kits are designed as complete, no-guesswork packages rather than loose parts.

Optimize the front end of your Harley-Davidson with the Burly Brand Fork Preload Adjuster for 39mm forks. This RAW machined aluminum adjuster replaces your stock fork cap, giving you 20mm of crucial adjustment range to dial in your ride.

Achieving the perfect suspension setup is key to a confident and comfortable ride.

No more guesswork or costly trips to the shop – just precise adjustments with a simple hex key.

Common questions

How much preload adjustment does this provide?

This Burly Brand Fork Preload Adjuster offers 20mm of adjustment range. Turning it clockwise increases preload for a stiffer front suspension, and counter-clockwise reduces it.

Do I need special tools for installation?

No, installation is straightforward. You will need a hex key for adjustments (which may be included or a standard size) and basic socket tools to remove your existing fork caps.

Will this fit my 49mm forks?

No, this specific adjuster is designed only for 39mm forks. If your motorcycle has 49mm forks, Burly Brand offers a different adjuster model tailored for that size.

Look fantastic on Triumph Bonneville T120

Thanks to Stuart Fillingham's YouTube video, I bought these. Couldn't be happier. A bit heavier than I expected but that just goes to the ruggedness of these panniers.

Love. These.

The style is awesome! Love the relaxed look with all the trim to make them classy too. Easy to get in and out of...really like the flip fully open and the finger hole snaps.<br />Great bag, perfect size for the HD Street 750!

Sweet

The Dark Oak canvas bags fit my Olive Gold Harley Slim S great! The fit and finish add that nostalgic look to an already classy bike. They are a bit small, but I didn't need to move my signals to make them fit, though plate relocation would be required had I not already moved it. They are a great addition and I can't wait to show them off.

Burley Brand Voyager throw over.

Styling looks excellent. Build quality looks good, but there are definitey gaps in the lid closures where the rain can get in. The buckle snaps are easy to open and close but the tend to come unsnapped from just normal freeway riding speeds. The bags still stay closed because of the strong clips,, but the cool-loking bucklet snap come open. Would I but them again... probably. I might look at the black ones for better weather proofing. The olive onmes do looks fantastic, though, on my flat black T100. Very easy to take off and put on; takes only a couple of minutes. I used a universal rack assembly.
