Used KTM Parts

At Sun Coast Cycle Sports, our warehouse in Odessa, Florida holds a rotating inventory of used KTM motorcycle and off-road parts sourced from salvage and donor machines. We photograph and catalog every component under its own SKU before it goes live on the site, and domestic shipping is included at no extra cost. Models represented across our shelves span Super Duke 990, Super Duke 1290, Adventure 990, Adventure 790, RC8, 950 SM, SMT 990, Duke 640, 390 Duke, and select off-road platforms like the SX65, SX85, 250 EXC, and 620 RXC. Inventory turns over constantly because almost every KTM part we list is a single piece pulled from one specific donor bike.

KTM model overview

KTM is an Austrian manufacturer headquartered in Mattighofen, with a motorsport identity built on Dakar Rally victories, motocross world championships, and an aggressive "Ready to Race" product philosophy. The company is part of the Pierer Mobility Group, which also owns Husqvarna Motorcycles, GasGas, and previously held a stake in MV Agusta. This corporate relationship is critical for used parts buyers: KTM and Husqvarna share engines, frames, and electronics across multiple model lines, meaning a donor Husqvarna can supply compatible parts for a KTM and vice versa.

KTM's street lineup centers on the Duke naked bike series (from the 125 to the 1390), the Adventure dual-sport/touring range, the RC sport bikes, and the Super Duke hyper-naked platform. Their off-road catalog covers motocross (SX), enduro (EXC), and rally machines. KTM engines are characterized by compact single-cylinder LC4 units, the LC8 75-degree V-twin (used in 950/990/1090/1190/1290 models), and the more recent LC8c parallel twin powering the 790/890 family.

Models and year compatibility guide

Common failure points and frequently replaced components

Super Duke 1290 R / EVO (2014-present): Wiring harness misrouting on 2020-2022 Super Duke R and Super Duke R EVO models can cause electrical short circuits and engine stalls. NHTSA 22V900 covers 1,040 units; dealers inspect and reroute the harness with added protection. The 2016-2017 Super Duke GT had a defective preformed fuel hose that could crack and leak (NHTSA 17V194, 487 units). Fuel pump seal failures were addressed via a technical service bulletin on 2017 models across the 1090 and 1290 platforms.

Super Duke 990 / Adventure 990 / SMT 990 (LC8 V-Twin, 2005-2013): The clutch slave cylinder is the most notorious weak point on all LC8 models. The OEM piston seizes over time, causing hydraulic fluid leakage and loss of clutch actuation. Aftermarket replacements from Oberon and Sigutech are considered permanent fixes. Water pump seal failure is a documented service item, typically presenting as a flickering oil pressure warning when the engine is warm. Voltage regulator overheating affects Super Enduro R models disproportionately because the factory mounting position under the seat exposes it to exhaust heat, causing unregulated overcharging and boiled battery electrolyte. Fuel injection calibration issues on 2007-2009 models caused stalling, erratic throttle response, and abrupt on/off power delivery that KTM addressed through ECU map updates. The immobilizer system on 2010-2011 models occasionally locks out owners by failing to recognize the key transponder.

950 Adventure / SM / Super Enduro (2003-2007): The early LC8 clutch had a design flaw involving the oil jet and pushrod that caused clutch dragging. KTM issued a technical bulletin and updated the parts. Swingarm chain slider bolts on 2006-2007 models worked loose and could lock the rear wheel; a safety recall required removal and application of Loctite 243 to the fasteners. Starter clutch failures in the first two model years produced a metallic hammering sound during cranking.

790 / 890 Duke and Adventure (LC8c Parallel Twin, 2018-present): Countershaft output seal leaks are endemic to early production 790 models, with multiple owners reporting oil accumulation on the skid plate and around the sprocket area. KTM dealers replace the seal with an updated kit, though some owners report repeat failures. Valve cover gasket weeping at the half-moon sealing surface is widespread across both 790 Duke and 790 Adventure platforms; the fix involves replacing the gasket with additional sealant at the half-moon joints. Dashboard fogging and exhaust header leaks have been reported on 790 Adventure R models. The 790 Adventure (2019-2020) was also subject to a recall for rear brake hose routing.

390 Duke / Adventure / RC 390 (2013-present): The 2022-2024 KTM 390 Adventure and Husqvarna Svartpilen/Vitpilen 401 share a faulty e-throttle assembly from supplier Uno Minda that allows moisture intrusion, causing sudden loss of throttle response. NHTSA 25V598 covers 9,070 units. The ECU drops the engine to idle without warning, and the issue persists until the ignition is cycled. KTM replaced throttle units with a redesigned part produced after May 2024.

RC8 / RC8R (2008-2015): Oil vaporization into the airbox is a known characteristic on track-ridden examples. The RC8R addressed this with a factory oil catch bottle kit (dual-hose setup). Head gasket and valve cover oil leaks are reported on higher-mileage units. The balancer shaft end seal can wear and allow pressurized oil to blow into the airbox. As a limited-production model, replacement parts are increasingly sourced from donor machines.

Continental TKC 80 tire recall (cross-model, 2019-2023): NHTSA 22V588 covers KTM Adventure models equipped with Continental TKC 80 tires that developed tread rubber groove cracks during testing. Continental replaced affected tires free of charge at authorized KTM dealers.

Frequently asked questions

Q: Can I use Husqvarna 701 parts on my KTM 690?

From 2016 onward, the KTM 690 and Husqvarna 701 share the same LC4 engine. Internal engine components, starters, clutches, and many electronic modules interchange directly. The frame, subframe, and bodywork differ between brands but the mechanical core is identical. Earlier 690 models (2008-2015) use a prior version of the LC4 that does not share parts with the 701.

Q: Are KTM Super Duke 990 parts compatible with the Adventure 990?

The Super Duke 990, Adventure 990, and SMT 990 all use the same LC8 V-twin engine. Engine internals, the clutch slave cylinder, water pump, alternator, starter, and most engine-mounted accessories interchange across these models. Frames, bodywork, and suspension are platform-specific, though the rear shock mounting dimensions overlap on some variants.

Q: What is the e-throttle recall on the 390 Adventure?

NHTSA 25V598 covers 2022-2024 KTM 390 Adventure and 2022-2023 Husqvarna Svartpilen/Vitpilen 401 models. Moisture can enter the electronic throttle assembly and cause a voltage signal fault, which makes the ECU drop the engine to idle without warning. KTM replaced affected throttle units with a redesigned, better-sealed component. Riders who paid for throttle repairs prior to the recall may be eligible for reimbursement.

Q: Do KTM EXC enduro parts fit Husqvarna FE/TE models?

Within the same model year, KTM EXC-F four-stroke enduros and Husqvarna FE models share identical engines, frames, subframes, and most hardware. Plastics, graphics, and some trim pieces differ. Two-stroke KTM EXC models correspond to Husqvarna TE models in the same way. This interchange applies broadly from 2014 onward when Husqvarna moved to shared KTM platforms.

Q: Why do LC8 V-twin KTMs eat clutch slave cylinders?

The OEM hydraulic clutch slave cylinder on KTM's LC8 engine uses a piston that tends to corrode and seize over time, especially if the hydraulic fluid is not changed regularly. Once the piston sticks, fluid bypasses the seal and the clutch loses actuation. Aftermarket replacements from companies like Oberon use corrosion-resistant materials and are widely regarded as a permanent solution. Budgeting for a slave cylinder replacement at purchase is standard advice for any used LC8 buyer.
