The 2004 BUELL XB12R is a solid performer with an 88.6% first-time pass rate, comfortably above the UK average of 80%, and dangerous defects are rare at just 7.3% of vehicles. This is a genuinely reliable bike by MOT standards, with no major red flags for prospective buyers.

These machines have covered a modest average of 10,621 miles, which is reasonable for a nearly 20-year-old performance bike, and they typically rack up just 1.03 failures and 2.6 advisories per test. Before buying, have a pre-purchase inspection focus on the 2.6 advisories that these bikes commonly accumulate—likely minor wear items—to make sure you're not inheriting someone else's deferred maintenance.
