About the Suzuki SP370
Practical service parts for Suzuki’s late-1970s four-stroke SP370 trail bike.
Suzuki introduced the SP370 in 1978 with an air-cooled four-stroke single-cylinder engine. For a trail bike returning to regular use, this selection brings together oil filtration, clutch service and rear brake parts. Keep the exact SP370 identification with the engine and chassis details recorded during restoration.
Choosing SP370 service parts
Compare the oil filter reference with the fitted engine, and record steel clutch plate quantities separately from other plate types. For rear brake work, identify the drum and shoe profile. Fork service requires extra care: the collection contains seals with matching inner and outer diameters but different stated heights, so use the full dimensions and profile.

Steel clutch plate selection
Match the plate material, profile and position to the clutch being repaired. One steel plate does not replace the entire stack or establish the number required.
Fork seal height needs checking
Two listed fork seal options share 36 mm inner and 48 mm outer diameters but show different heights. Compare the full profile and removed seal markings before ordering; diameter alone is insufficient.
