1973 Honda bikes

1973 Honda TL 125 Trials (Honda code 335)


 

 
 
At the end of 1972, Honda launched the TL125, known in Japan as the name of BIALS.
Engine used for it was the 121,9cc (54 X 49,5mm) two valve sohc from the Honda SL125 model, lowering its compression from 9:5 to 8:1
Little Honda Tl 125 was very popular, Honda had big success in the US, Japan and Europe.
 
The TL 125 first in 1973 and the TL 250 in 1975 were the first production Honda Trials motorbikes. The begining of the nice and amazing history of this brand on Trials line narrated here at this webpage: The Honda Trials History.
 
In 1973 three Japanese riders took place at SSDT with the little TL 125, NishiyamaNarita and Mazawa.
 
Peter Gaunt was one of the first UK engineers who in developed a transformation using a Honda bike as a base. The bike was sold under the Jefferies Honda name, this is because Jefferies bikes, located at Shipley, Yorkshire, was the dealer.
Honda seriously began on the Trials Bike competition in 1974 with one of the most important persons on the Honda Trial Bikes History: Sammy Miller. He was a key person on the Honda Team, as a rider, as a bike development and as a strategist.

The Honda TL 125 had a lot of series, for sure the most successful Honda trials.
From 1972 to 1988 little Honda TL125 had basically two series: The Japan Bials series and the US TL series:

1974 Harry Fairbairn's Honda 125 trials
 
 
 

 In 1974 after some Japanese riders did participate aboard little 150cc Honda machines (based on the 125s) in the Scotish Six Days Trial, Harry Fairbairn, Scotish Honda dealer, made a special bike based on the XL 125 Trail. The bike was modificated to reduce the weight, achiving a reasonables 180lbs, also special mudguards, exhaust system, and foldable footrests were made. These bikes were sold by Fairbairn at 300L. 

 
 I have no notice of any of these bikes surviving today. Also no fotos.
