The Colleda 250TT pairs a backbone type frame with a 250 cm³ 2-stroke 2-cylinder engine that generates 18 PS. It also features a rotary 4-speed transmission, Earles forks at the front, and a pivot cushion/swingarm combination at the rear. One talking point of this model was its sophisticated design that included a large headlight with a prominent nacelle, streamlined turn signal bodies, and fin-shaped rear turn signals. The Colleda 250TT is also notable for its puncture-resistant and easy-to-repair tubeless rear tire.

The Colleda 250TP is a slightly simplified version of the Colleda 250TT, featuring modifications such as a pipe cradle frame and telescopic type suspension. However, excellent riding performance was ensured by using the same engine and transmission.

The Colleda 250TM combines a plunger type rear suspension with a channel frame, and has an exterior appearance that resembles the 125 cm³ ST3. It features a 250 cm³ 2-stroke 2-cylinder engine and a large rear carrier for business uses behind a saddle type seat.

A notable feature of the Colleda Twin Ace 250TA is Suzuki’s original integrated Jet Line styling that flows from the headlight to the fuel tank and tool box. This styling is based on the design of Colleda Sel Twin that debuted the previous year, with various modifications to form a closer harmony between the expression of solidity and speed. The 2-stroke 2-cylinder engine is equipped with an electric starter and generates maximum horsepower of 18 PS. It adopts a twin-carburetor system for higher acceleration performance and excellent fuel economy of 70 km/L (40 km/h steady state fuel economy*), equivalent to that achieved by a 4-stroke 1-cylinder engine. This is also the first mass production model in Japan to be equipped with hydraulic brakes. Safety-oriented features such as a synchronized front/rear wheel brake system are another major characteristic of this model.

The Colleda 250TB is a sporty version of the Colleda 250TA and is notable for its two-tone white and red paintwork, The 250 cm³ 2-stroke air-cooled 2-cylinder engine features an enhanced intake and exhaust system, which increases its horsepower from 18 to 20 PS. The intake system utilizes twin carburetors to achieve the ideal air-fuel mixture, thereby improving acceleration and high-speed performance. This intake system also helps to realize fuel economy of 70 km/L (40 km/h steady state fuel economy on paved roads*). The Colleda 250TB also features a hydraulic rear brake in addition to the mechanical front brake.

The Colleda 250T10 features a 250 cm³ 2-stroke air-cooled 2-cylinder engine equipped with a twin carburetor system. This engine generates maximum horsepower of 23 PS and maximum torque of 20.6 N·m, as well as excellent steady-state fuel economy of 55 km/L*. Thorough attention was paid to the exterior finish by adopting parts such as a plated front fender, upright pipe handlebars, and a double seat with a sub carrier. Other features include a rotary 4-speed return change transmission and a hydraulic rear brake.

The Colleda 250T20 was developed with the aim of producing the fastest 250 cm³ model in the world. It adopted some of the latest technologies from victorious World Grand Prix Road Race factory machines, such as aluminum cylinders, the first Cylinder Crank Injection (CCI) system adopted on a motorcycle, and the first 6-speed transmission on a mass production model. This model realized class-leading performance in every aspect, including being the first 250 cm³ model to reach a speed of 100 mph (160 km/h) and successfully being ridden at a speed of at least 120 km/h for 24 hours non-stop on highways in the U.S. The Colleda 250T20 can be described as the origin of Suzuki’s strategic global models.

The GT250 debuted alongside the GT500 and GT350 as part of Suzuki’s GT series, replacing the existing T series of models. Its 250 cm³ 2-stroke Cylinder Crank Injection (CCI) engine features a 6-port exhaust cylinder head, resulting in dramatically higher exhaust efficiency. This engine generates maximum horsepower of 30.5 PS and maximum torque of 27.7 N·m. It is paired with a close-ratio 6-speed transmission that makes effective use of the available engine power under a wide range of riding conditions. In the same way as the GT500 and GT350, the styling combines essential motorcycle design elements such as a down type muffler, large-capacity 15-liter fuel tank, and chrome-plated fenders. The spacious seat realizes impressive cushioning and restoration performance.
