The Suzuki TS series is a family of two-stroke, dual-sport motorcycles made by Suzuki since 1969. The series was the first Suzuki trail bikes sold on the mass market. Most of the TS line had an air-cooled engine and most models were introduced alongside the closely related TM (Motocross) or TC (trail) models, TF (farm) and also the DS (for Dirt Sport, which had no turn signals, and simplified lighting) which in most cases shared engine and chassis designs. Suzuki's first mass market motocross bike, the TM400 Cyclone, was introduced in 1971 and was based on the TS that first sold in 1969. A TS185ER model was available in a few countries.
Models.
The TS185 is lighter than the 125 by a few pounds, and has nearly the power of the 250 but with a much more free revving motor. The 250 is heavier than the 185. The larger TS series, 125 and over had piston port engines while the smaller TS series-90 and 100 had rotary valve induction, until the introduction of the ER series motors. With the only major redesign of the motors of this series, the new range shifted to a combined reed-valve and piston port type.
A factory race kit was available for the TS90 which consisted of an expansion chamber, light piston and rings, carburetor, and harder (colder range) plug and head which increased the size to . In the North American market a 175cc race kit was available for the TS185. The 175 size was to match an established class. It consisted of an expansion chamber, new cylinder and head, piston, thin rings, larger carburetor, and much lower gearing. Different gearing was available for most models. The TF model (Mud Bug) was developed in the early 1970s and sold mainly in New Zealand and Australia. The TF series was made in three sizes; 100 cc, 125 cc, and 185 cc engines. These bikes were based on the ER range. The TF125 is still in production. It has left-and-right side stands with large bases, a large rear carrier, headlight and lever protection, a single seat, bash plate, large mud flaps and knobby tyres.
The very similar TC series was based on the TS series, with dual range gearboxes. The TC185 also has Dyno Starter, a DC electric combined DC generator/starter motor.
Model names.
Model names vary by region. The 'ER' series in Britain such as the TS100ERN, the TS100ERT and TS100ERX were air-cooled twin-shock models made from 1979 to 1981 with only very minor technical and cosmetic differences between them. They were then superseded by the mono-shock TS100X model.
The TS50ER model was the predecessor to the later TS50X which ended production in 2000.
