Sun Coast Cycle Sports carries individually inspected used parts for the Husqvarna TC 85, the brand's premier 85cc two-stroke motocross machine built for junior racers transitioning toward full-size competition bikes. Produced from 2014 to present with an 84cc liquid-cooled two-stroke single-cylinder engine, the TC 85 comes in two wheel-size configurations (17/14 and 19/16) to accommodate different rider heights. Each part on our shelf is photographed, cataloged under its own SKU, and ships from our Odessa, Florida warehouse.
TC 85 generation and parts compatibility
| Generation | Years | Engine | Key differences |
|---|
| Gen 1 | 2014-2017 | 84cc 2-stroke single | Initial KTM-era platform, WP AER fork, Keihin PWK carburetor |
| Gen 2 | 2018-2024 | 84cc 2-stroke single | Updated graphics yearly, refined suspension settings, hydraulic clutch added |
| Gen 3 | 2025+ | 84cc 2-stroke single | All-new chromoly steel frame, redesigned WP XACT suspension, new single-piece swingarm, revised bodywork |
Within Gen 1 and Gen 2, the TC 85 received mostly cosmetic updates year over year, so parts interchange broadly within each generation. The 2025 redesign introduced a completely new frame, subframe, swingarm, and bodywork that are NOT compatible with 2014-2024 models. Engine internals remain largely similar across all years, though cylinder head and ignition components changed for 2025. The TC 85 shares its KTM-group platform with the KTM 85 SX. The engines are essentially identical between the two brands, and many engine internals interchange. However, bodywork, subframes, graphics, and some chassis components are brand-specific and do not cross over.
Common TC 85 failure points and replacement parts
Top-end wear: As a high-revving two-stroke competition engine, the TC 85 requires regular top-end rebuilds. Piston and ring replacement is typically needed every 40-60 hours of racing use. The cylinder may need replating after multiple rebuilds.
Power valve linkage: The exhaust power valve linkage can wear and develop play over time, affecting power delivery. Inspect linkage pins and seals during top-end service intervals.
Clutch wear: Junior racers learning clutch control tend to burn through friction plates quickly. The hydraulic clutch system introduced on later models improved feel but the slave cylinder can develop leaks.
Suspension seals: The WP forks see hard use in motocross conditions. Fork seal replacement is a frequent maintenance item, especially on bikes ridden in dusty or muddy environments.
Commonly replaced TC 85 parts
- Pistons, rings, and cylinder assemblies
- Clutch plates and clutch slave cylinder
- Fork seals and suspension components
- Plastics, fenders, and shrouds
- Exhaust pipe and silencer
- Chain, sprockets, and rear wheel bearings

Frequently asked questions
Q: Will KTM 85 SX parts fit a Husqvarna TC 85
Engine internals like pistons, bearings, and crankshaft components are shared between the TC 85 and KTM 85 SX within the same model year. Bodywork, subframes, seats, and graphics are brand-specific and will not interchange. Always match parts to the specific model year, as the 2025 generation introduced significant changes across both brands.
Q: Are 2014-2024 TC 85 plastics interchangeable
Plastics interchange within Gen 1 (2014-2017) and broadly within Gen 2 (2018-2024), though mounting points and shapes received minor revisions in some years. The 2025 redesign uses completely new bodywork that does not fit earlier models.
Q: What is the difference between TC 85 17/14 and 19/16
The numbers refer to wheel sizes in inches (front/rear). The 17/14 has smaller wheels suited to shorter riders, while the 19/16 has larger wheels for taller riders. Frames, engines, and most components are identical between the two variants. Wheels, spokes, tires, and fork/swingarm lengths differ.
