Built for just two years the T25T (1970 and ‘71) was an attempt by the Triumph/BSA brain trust to capitalize on the scrambler craze.
The styling was good with a unique exhaust setup but they had a reputation for heavy vibration and weak gearboxes. Whatever the reason they just didn’t sell very well which puts them squarely in today’s collectible market.
The lack of information about this model is probably related to the number of sales. I do know there were several variants including the SS street scrambler that had ‘hugger fenders’ and road tires. The T had fender clearance and knobbies.
The 1971 Triumph T25T used a 247 CC air cooled single cylinder overhead valve motor that made 22 HP and a four speed transmission with drum brakes for and aft.
This particular 1971 Triumph T25T (VIN # T25T DE10661) is in Pagosa Springs, Colorado and is listed with 5,137 miles in ‘very nice original condition’. It does look to be mostly there, I think there should have been a ‘bash plate’ between the cradle tubes. The bike currently has 9 bids to $1,723 with reserve not met
