Frequently Asked Questions

How much preload adjustment does this give me?

20mm of adjustment range via a standard hex key. Turning clockwise increases preload for stiffer suspension.

Do I need any special tools to install this?

No — installation is straightforward. You'll need a hex key (included or standard size) and basic socket tools to remove your stock fork cap.

Will this fit my 49mm forks?

This adjuster is designed for 39mm forks. If you have 49mm forks, Burly Brand offers a different part number.

Can I adjust preload while riding, or do I need to stop?

Preload is a static adjustment best done when the bike is parked. Make small adjustments and test-ride to dial in your preference.

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.

Commuting, not touring

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.
