1989 Honda TLM260R (nice but not four stroke engine!!)


















Based on two stroke Spanish Montesa engine, Honda made these bikes for Japanese market. The TLM's never came to Europe or US market.
This was the "temporary" change made by Honda Trials Bikes, but no later, Honda returned to his Four-Stroke engines.

1983 Honda Alpha 240
















Thanks to Patrick from Aspen Café*, today I'm glad to rescue this nice bike and history.
In 1983 French engineer Jacques Coll* developed this advanced frame based on a Honda XL125 engine.

Jacques Coll designed a very special frame, mixing alluminum parts and inox steel detachable rear sub frame.
He made a very clever and advanced solutions as the air filter at top (light position, between front forks) and gas tank under the seat. With this solution the bike has everytime clean and fresh air n the combustion and moving down the gravity center. This solution was also applied at same time in Sweeden by the hand of Maltry brothers to develop the also advanced Trans Ama bike.



















Today some actual bikes as Sherco Trials are applying some of these solutions, but 27 years later!!!
This advanced engineer also put a monoshock as a rear suspension, achieving 199mm displacement, reducing weight and also moving down the Gravity Center.

* Jacques Coll was a clever and advanced French engineer. He was working at Militar Aviation service on the begining and leter became an outstanding engineer working in several projects as this nice ALPHA bike. He was the engineer who developed the first Sherco engines and also the first four-stroke Sherco engine. Unfortunatelly world of trials bikes lost one of their best engineers, Jacques Coll died in 2006.

* Aspen Cafe is a nice and long tradition five generation Cafe placed in French Alps, more info at: www.aspencafe.com

1983 Honda TLM 50

















For the young beginners Honda made in 1983 this nice two stroke engine little machine, The TLM 50.
Design was fully based on the TLR's series. Red with white, blue stripes, red frame and black painted engine. This is not a "really" Honda machine, due to his two stroke engine, but I wanted to introduce here because may be some Honda four stroke Trials fans were lucky to start with this model.

On this picture (thanks to Andrew Hoddler) the Honda TLM 50 in action with a young rider.

Thanks to Dean Swann. Nice Honda TLR 250 with RTL 250 cc engine fitted.

These TLR bikes were a essential milestone on the Honda trials history.
The bike was offered in two different engines and practically same frame, TLR250 and TLR200. The first one had a HRC based (but not developed) 249 cc displacement, 4 stroke and two valves engine. Second one, the TLR200 had 194 cc 4 stroke engine.
From Australia Steven Hervie sent me this well performed Honda TLR 250

1981 Honda RTL 360






At only 18 years old, Honda gave the powerfull RTL 360 to Eddy Lejeune.
Kiyoteru Hattori was another rider from Honda Trials Team that also rode the RTL 360.

First Honda 360 prototypes were made early 1979, Rob Shepherd was one of the first to ride on this big machine. The new machine was the most powerfull trials bike never made. After several problems at first time, the bike was revised by Honda due to a overheating problems.
After a lot of engine improvements and long time, at end 1979, the 360 runs as a new engine, so different comparing the old one.














Thanks to Pat for this nice picture from Honda meeting at ASPEN Cafe. in front we can see a nice RTL360.
In accordance to Tommy Sandham's journalist expert the RTL 360 was the best bike he never rode, on the same way also he reported that in opinion of the top British riders have ridden the bike, it was the best trials bike of the moment.

As telling the 1983 American Motorcycles magazin, Schreiber said "Eddie's an excellent rider, but the bike is also excellent in muddy and wet conditions.















There is small quantity RTL 360 survivors today. This pictured one owns at Italian collector. Maybe one of the most expensive Honda trial bikes and of course difficult to see.

















This picture taken by Antonio Maugeri in 1982 shows the first Lejeune's RTL 360.
Painted all Red color, Silevr grey engine, Silver aluminum wheels, Today, the bike is still alive in France, belongs to a French collector.
Thanks for the picture Antonio!!

1981 Honda RS250T




Same as RS200T models RS250T was made following same philosophy. The bike was designed and manufactured for competition use only.
The bike did not conform to federal motor vehicle safety standards and operation on public streets, roads or highways is ilegal.

It appears that RS250T production was lower than TL and RS 200. In fact first development was made late on 1981 and the production was done by the renamed RSC, the new HRC Honda Racing Corporation.

The RS250T was the excellence of the RS's range. Very nice and competitive bike, based on the same RS200T chassis but modifying a little bit some parts to introduce the powerful 15Hp 249,8cc HRC engine. Like the RS200T rear wheel axle was perforated on all his extension, RS250T had also the front wheel one perforated.


The bike has no lights and any electrical installation. The front upper forks were covered by a nice aluminum plate.



Front forks were improved from the RS200T adding a connection link between both fork tubes in order to balance the inner air pressure.


To reduce the fuel tank width and allow to assemble the high performance Keihin 22, the RS250T had a really special shape fuel tank.



Original RS250T fuel tank color was Honda Red Accent painted. This nice unit (from Spain) was metallic silver/Honda Red Accent mixed painted on a personal choice of color.


The final appearance of the bike is really a professional prototype!!



The RS250T silencer, HRC logo engraved and two exhaust outlet.


The RS205T silencer had two exhaust outlets and the de new HRC engraved logo. The TL200RII and RS200T models had only one and the RSC engraved logo.

The RSC engraved logo, one exhaust outlet form RS200T

A very nice aluminum silencer replica for RS200T, RS220T, Honda SEELEY and TL200RII.


An other difference between RS200T and RS250T is the color of the wheels, the RS250T had yellow anodized finish, the engine had also different color painting, the RS250T was black color instead Metallic Silver.

In some RS250T units we can see special air expansion chamber on exhaust. Not all the units had this feature and not all the expansion chambers were made on the same way or shape, this is something that was hand made specially for every unit.
