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.

The main year ranges above follow the supplied application information. KTM’s original parts finder confirms 55140001000 on representative earlier applications, including the 2009 300 EXC Six Days and 2012 250 XC-W. It confirms 55140001100 on later examples such as the 2014 250 EXC, 2015 200 EXC, and 2017 Freeride 250 R.
Model names can vary by sales region. For example, an application sold as an XC-W in North America may have a related EXC designation in another market. Use the complete model code and OEM starter number as the primary fitment references.

Fitment FAQ
Will this part fit my specific model and year?
This starter motor is intended for compatible models including:
2008–2016 KTM 250 XC-W
2009–2016 KTM 300 EXC Six Days
2014–2017 KTM Freeride 250 R
2013–2016 KTM 200 XC-W
Selected KTM 200 EXC, 250 EXC, and 300 EXC applications using the same starter configuration
Your original starter should use 55140001000, 55140001100, or a confirmed interchange number and match the listed nine-tooth gear, dimensions, mounting design, and terminal position.
Do not rely only on engine displacement or the model year. KTM used different starter and starter-drive components across its 200cc, 250cc, and 300cc two-stroke platforms.
Do I need to match the OEM part number?
Yes. Matching the complete KTM part number is one of the most reliable ways to confirm fitment.
This starter is intended to replace:
KTM 55140001000
KTM 55140001100
94078610
J & N 410-54153
J & N 41054153
Lester/WAI 19091N
Arrowhead SMU0505
Mitsuba SM16
Your original starter does not need to show every number listed above. At least one compatible KTM OEM or confirmed interchange number should match.
KTM’s official parts diagrams show 55140001000 on earlier representative applications and 55140001100 on later representative applications.
What models or situations does this part not fit?
This starter motor is not intended for:
KTM motorcycles using a different OEM starter number
Four-stroke EXC-F, XC-F, SX-F, or XCF-W models
KTM 250 SX or 300 SX models without the matching electric-start configuration
Later TPI or TBI models using a different starter system
KTM 125cc or 150cc motorcycles
Applications requiring a different number of drive teeth
Starters with a different gear diameter or housing length
Models with a different electrical terminal position
Motorcycles with engine swaps or modified starting systems
Applications where the original starter or mounting design looks different
Do not assume that every KTM 200, 250, or 300 two-stroke motorcycle uses this starter.
What should I check before ordering?
Before ordering, confirm:
Motorcycle brand and complete model
Exact production year
Model suffix, such as XC-W, EXC, EXC Six Days, or Freeride R
Two-stroke engine configuration
KTM OEM or confirmed interchange number
12V electrical system
Nine-tooth drive gear
11 mm / 0.43 in drive-gear diameter
123 mm / 4.84 in overall length
54 mm / 2.13 in overall width
Listed 15 mm / 0.59 in mounting measurement
Exact measurement points shown in the product images
Electrical terminal position
Mounting-ear and housing shape
Starter-drive and Bendix condition
O-ring and sealing-surface condition
Also inspect the battery, starter relay, fuse, cables, wiring, ground connections, Bendix gear, crown wheel, and starter-drive cover. A fault elsewhere in the electric-start system can cause symptoms similar to a failed starter motor.
