Honda Motor Co has developed a lightweight and slim trial bike equipped with a newly designed 4-cycle engine (244cm3) that is suitable for trial sports and touring, which has been gaining popularity in 80s.

The Honda TLR250R, which was released in April 30th 1986 as a trial sports bike, was the world's first "split center tank system," in which the fuel tank was divided into a main tank (4 liters) and a sub-tank (2 liters) under the seat. ” was employed. As a result, while achieving a slim body that is indispensable as a trial vehicle, it was also practical as a model with a number (can be driven on public roads). The air-cooled 4-stroke single-cylinder OHC engine with a displacement of 244cc is mounted on a lightweight and highly rigid vertical oval cross-section frame, and the transmission is a 6-stage return type. The fuel efficiency achieved was 55.3km/L (at 50km/h level driving), so theoretically it was possible to cruise 300km with one refueling. The swingarm is made of aluminum, and the rear suspension is pro-link. For the front and rear wheel spokes, TL spokes (Tangent Located Spokes) with excellent strength and elasticity are used. The minimum ground clearance is 310mm, and the shape of the engine protection plate is flat. The steering angle was 68 degrees on both the left and right sides.

1986 Honda TLR250R Main Specifications

Equipped with an air-cooled 4-stroke single-cylinder 244cc engine that is lightweight and compact, a 6-speed transmission, and front and rear drum brakes (mechanical leading trailing). It exhibits powerful output characteristics in the extremely low to low/mid speed range, which is frequently used in trial sports, and smooth output characteristics in the high speed range, making it suitable for trial sports and touring. ing.
The frame uses a lightweight, highly rigid side-pipe diamond frame with a vertical elliptical cross section. At the same time, we have achieved a slim body and a weight reduction of 93 kg (dry weight), which is essential for trial vehicles. In addition, the world's first trial vehicle adopts a split center tank system, which divides the fuel tank into two: a main tank (4L) and a sub tank (2L) located under the seat. In addition to realizing ground clearance, it is easy to handle with the adoption of a flat engine protection plate and pro-link suspension.
In addition, due to excellent fuel economy (55.3km/l: 50km/H level running test value), 6L fuel tank capacity, 6-speed transmission, etc., it is also suitable for touring.
