Suzuki TS250 1972-1981 Factory Service Repair Manual

Classic Motorbikes' own year-by-year model history captures this bike's development philosophy perfectly: 1972's TS250J brought "little new," 1974 saw "no mechanical updates just graphics and paintwork," and 1975's model "remained virtually unchanged" — Suzuki spent years refining the TS250 in small increments rather than reinventing it, right up until a genuine ground-up cosmetic overhaul finally arrived in 1980. Known as the Savage in some markets, the TS250 built its decade-long reputation on being straightforward, reliable, and easy to live with rather than chasing outright performance.

Power comes from a 249cc air-cooled two-stroke single, a 70.0mm bore and 64.8mm stroke, delivering a claimed 22-26 hp depending on model year and roughly 20 lb-ft of torque, fed by a Mikuni carburetor (the VM28SC gave way to a VM28SH in 1973 specifically for improved mid-range fueling) through a 5-speed transmission with wet multiplate clutch. Genuine technical milestones across this run are worth knowing for anyone servicing a specific year: the 1971 TS250R (immediately preceding this range) had already introduced Suzuki's PEI pointless electronic ignition system in place of contact-breaker points, a change that carried forward through the rest of the model's life and meaningfully improved reliability over the earlier points-based ignition.

The most significant change within this specific 1972-1981 window arrived in 1980: a complete cosmetic redesign brought a new headlight cowl and a box-section swingarm, along with improved bodywork plastics — Bike-urious's own review of a late-production 1981 example, the model's final year, lists 22 hp, 20 lb-ft of torque, and a 288-lb curb weight for this final, redesigned configuration. Suspension throughout the range paired a telescopic, leading-axle, oil-damped front fork with a swingarm rear end running dual, coil-sprung, 5-way adjustable shocks, riding on a 3.00-21 front and 130/80-17 rear tire with expanding drum brakes at both ends. A 3.17-gallon fuel tank rounded out the package on later models. Because year-to-year graphics, exhaust shielding, and minor component changes varied considerably across this decade-long run, confirming the exact chassis and engine numbers against the specific model year remains the safest way to source correct parts and settings.

This factory service manual covers the procedures, torque specs, and diagrams needed to keep a 1972-1981 TS250 Savage's two-stroke engine and driveline running the way Suzuki built it.
