After sign a contract with Honda Japan, Sammy Miller made his own Team to develop the specific Honda for trial. Early 1974 he agreed to develop all the Honda range of trial bikes.
This Team developed in 1974 the new Honda trial 250cc based on the XL250 engine.

This was one of the first off-road bikes to feature a truly tuked-in upswept muffler. Its 4-valve OHC engine and chassis were uprated SL components.

The single cylinder, four valve engine was made all-alloy and equiped with a five speed gearbox. The final weight was only 90Kg.

From 1965 to 1973, First Honda Trials Bikes


Ken Ives' S90 Honda Trials Special



Ken Ives was a Honda dealers that made one of the first transformations from the "street" Hondas to ride on Trials races.
Ken Ives took a 1965 Honda S90 and made following modifications and improvements to well adapt on atrials riding:

He replaced the tyres, made a wider swing arm, of course improved the position and design of the foot rests, special exhaust, and add a bash plate to protect the bootom engine.

Engine was a lttle 90cc OHC, but strong enough to start on the first trial races.

At same time the Japanese Hideo Tanaka made his own transformation and rode with his S90. Tanaka, some time later was working on the RTL305 development.

In 2006, Mori Kojiro entered at Kinlochleven Scotish Pre 65 2-Day with this machine. 

Really a funny history!! Do not you think so?


The S90 original version

Later, around 1967, 68 Kevin Ives built a new Honda Trials bike based on the CB 160 and CD 175 engine.
Of course he replaced the wheels, tyres, rear suspension, also he changed the forks, special twin exhaust, frame with a lot of improvements like Camber angle, swing arm, reinforced sections, bash plate... Engine also was modified, low compression, lower gearing,..

Really a nice bike!!




Peter Gaunt's Honda History


Peter Gaunt riding a Suzuki trials

Peter Gaunt was the first engineer who in 1973 developed a serious 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. The bike was offered ad L469!!
Small series were made, no more than 20 units.

Almost two units still alive!!
Thanks to Carlo, from Italy, I found an original Peter Gaunt's Honda Jefferies,
and thanks generosity of Carlo to share these pictures, we can enjoy today with this nice bike survivor.






























I also found another original one, and thanks to John comments we know that the bike was from 1973. You can find pictures on the excellent and maybe the best Honda trials bike web page: www.honda-trials.com
The bike is from Adres Cook, and you can see it on following link:  http://www.honda-trials.com/_sgg/m1ma_1.htm


The Jefferies Honda XLS
Gaunt started using a XL250 (trail/enduro bike) but modifying several points in order to have a competitive trial bike.

Actually Peter Gaunt still ride and participates on races as Two Scotish Days with his wonderfull Royal Enfield. This bike has a lot of clever solutions, and perfectly explains how this engineer could make a transformation so successful. The bike is today in Spain bought by a private collector.
