Starter Motor for KTM 200/250/300 EXC XC-W Freeride 2008–2017 | 55140001100

Product Overview

Restore dependable electric-starting performance with this 12V starter motor, designed for compatible KTM 200cc, 250cc, and 300cc two-stroke off-road motorcycles.

Featuring a 9-tooth drive gear, compact metal housing, and direct-replacement configuration, this starter motor helps provide consistent engine cranking when the original starter becomes weak, slow, intermittent, or unable to turn the engine.

Its wear-resistant construction is designed to withstand repeated starts, engine vibration, heat, dust, mud, and demanding enduro or trail-riding conditions.

This replacement is intended for applications using KTM starter number 55140001000 or 55140001100. Because KTM used different starter-drive components across model years, compare the original starter number, gear teeth, mounting measurements, electrical terminal position, and housing design before ordering.
