The Trail Blazer was a 250cc single cylinder unit model T25T (Trail), mainly built for the USA market, whereas the T25SS (Street Scrambler) was built mainly for the UK market.

Main differences were the size of the front brake, trials tyres (road tyres on the SS model), and a high set front mudguard. There are a couple of other minor differences but not obvious to the unknowing. These also include an alloy fuel tank and folding rider footrests.
