The Fuellers and the Tubers

The XB range of Buells are known as "Fuellers" due to the fuel in the frame design. Older models are generally known as "Tubers" due to the tube frames.

Friendly rivalry exists between riders of Fuellers and Tubers, both believe their model to be the best, however most riders also have significant admiration for the others. It is generally acknowledged that both Tube framed and Fuel in the frame Buells are awesome bikes, with great handling and both get a "what the ??? is that?" kind of response from the general bike riding public!

The Buell XB range is renowned for amazing handling, winning Bike Magazine's Best Handling bike in 2006. That's true, if your Buell is setup right, but it can be a different experience if you just buy it and ride it.

Here we have the factory settings for the XB range, based on rider weight. Straight out of the manual, Buells recommended settings.

We also have some recommended settings from Buell factory racer Shaun Higbee.

Once you've tried the manuals, then you can follow racer  Sean Onipede of Go Star Racing's guide to setting up the suspension to suit you.

Tyre choice can be a personal thing, however there are some popular opinions on which tyres work and which are not so good on the XB.

In addition a link to the tyre thread within the forums, gives good advice from on tyre choices in general from Bryn Phillips at Bridgestone.

The XB Engine's are already quite highly tuned compared to the "standard" sportster engines they are based on. The XB9 is the engine to have if you want to build a bike with hp and higher revs, whilst the 12 is the better engine for torque and all out grunt!

There are some simple mods, which cost little, or even nothing, but give real world performance enhancements.

There are other mods, which certainly cost, but also deliver!

Intake, Exhaust, fuelling and transmission mods, all these are found here in the XB Performance pages.

Known Problems

OK confession time..... BUELLS AREN'T PERFECT!

Yes, I know that sounds bad, but it is true. But what's better is THE FACTORY KNOW THAT


Not all dealers are the same, but Buell generally have a great reputation for identifying problems with their bikes, issuing dealers with service updates and doing most work under warranty, EVEN IF THE FACTORY WARRANTY HAS EXPIRED!

Name another manufacturer with that kind of service standard!

Check your bike for factory recalls here.
