In Brief:

  • Great example of the rarer seen T25S Trailblazer
  • Finished in Orange with a Black seat
  • Just 4 former keepers
  • 5 owners in 54 years
  • Only produced for 1 year between 1970-1971

On the Surface:

A nice example of the short-lived Triumph T25SS Trailblazer, finished in bright Orange with a Black seat. This striking street scrambler retains its period-correct look and has had just 5 owners over its 54-year life, with only 4 former keepers.

Maintenance & History:

This machine comes with no documented history, but its minimal ownership over five decades suggests it has remained in enthusiast hands. With few of these models surviving in such presentable condition, it's an increasingly rare sight on the market.

The Model:

The T25SS Trail Blazer (Street Scrambler) was Triumph’s rebadged version of the BSA B25—an economical move to introduce a lightweight scrambler into their range aimed at younger riders. Despite its origins, the model performed well and received positive press at launch thanks to its handling and fun riding dynamics. Built mainly for the UK market, it featured small distinctions such as the front brake and mudguard when compared to its US-focused sibling, the T25T. Ultimately, it had a brief production run before Triumph returned focus to their more proven, established models.

Sale Insight:

Offered here is a rare opportunity to acquire a visually appealing and mechanically simple British single with rising collector interest. With only 5 owners since 1971, this T25SS would make a fantastic lightweight addition to any classic motorcycle collection.

Estimate:
£1,500 - £2,500
