Engine compatibility and applications
- Suzuki DT115 two-stroke: selected 1981-2001 applications using a listed OEM starter.
- Suzuki DT140 two-stroke: selected 1981-2001 applications using a listed OEM starter.
- Suzuki PU140 jet-drive: selected 1992-1996 applications where the complete starter specification matches.
- DT115/DT140 model suffixes and EFI/carburettor versions must be confirmed by original part number and physical configuration.
Compatibility rule: model and horsepower are not sufficient on their own. Confirm the engine year/serial range, electrical specification, pinion, rotation, mounting points and an OEM reference before ordering.

Frequently asked questions
Is this suitable for both DT115 and DT140 engines?
Yes, for the selected two-stroke applications listed above, provided the engine year/serial details and original starter specification match.
Will it fit every 115HP or 140HP Suzuki?
No. Horsepower alone is not a fitment check. It is not a universal starter for all Suzuki 115HP or 140HP engines.
What should I compare with my old starter?
Check 12V supply, CCW rotation, 9-tooth pinion, mounting pattern, terminal layout and one of the OEM references.
Does the package include cables or mounting bolts?
No. The package contains one starter motor; reuse serviceable original hardware only where the engine manufacturer permits.
Important: OEM names and part numbers are supplied only as compatibility references. This is a replacement component unless the listing explicitly states otherwise.
