Triumph T25 1971

Triumph presents two big bikes that can take a bad trail lightly.

The Triumph Trail Blazer. The Triumph Blazer SS.

Each packs 250ccs of muscle in a lighter-than-ever trail bike.

Each one will take you as far as you want to go, on the trail or off.

Because they're true Triumphs and the lightest 250's that Triumph has ever delivered. From the vibration-protected headlights to the tucked-in tail pipes they're radically improved.

See the next page for some of the feature-by-feature facts.
