2018 TC 50 - Pros & Cons
Strengths
-
🔧
Fuel injection: The fuel injection system delivers crisp throttle response and reliable cold starts regardless of altitude or temperature.
-
🛑
Strong front braking: The single disc front brake gives excellent stopping power and responds well to aftermarket braided lines.
-
📏
Accessible seat height: At 684 mm, the seat height is approachable for a wide range of rider heights and builds confidence in low-speed manoeuvring.
Considerations
-
⛽
Modest fuel capacity: The 2.30-litre tank means more frequent fuel stops on longer rides, which is worth planning around on touring routes.
-
⚙️
Chain final drive upkeep: Chain final drive needs regular cleaning, lubrication and tension checks to get full life out of the sprockets.
Wear Points & Servicing Notes
Fuelling & injector care
Fuelling comes from fuel injection. Systems like this are largely maintenance-free beyond keeping fuel quality decent and injectors clear - a fuel-system cleaner every service interval is cheap insurance.
Brake disc and pad wear
The single disc front brake gives strong, progressive stopping power. Disc thickness and pad depth are worth checking at every tyre change, since worn pads can score the disc surface.
Suspension condition on used examples
Up front, the TC 50 runs WP-USD, AER 35, 35 mm and WP shock absorber at the rear. On a used example, check fork seals for weeping oil and test the rear linkage for play - seals are a relatively cheap fix but useful when negotiating price.
Final drive maintenance
Final drive is by chain - expect to clean and lube it every few hundred kilometres and check tension regularly; a neglected chain wears the sprockets faster than the chain itself.
Frame & chassis check
The frame is Central-tube frame with double-cradle - worth a visual check for corrosion or impact damage around the head-stock and swingarm pivot on any used example, since frame damage is far costlier to fix than any service item.
Low-speed handling
At just 41.5 kg, the TC 50 is light enough to manhandle easily at a standstill - one of the practical advantages of its class.
TC 50 - Buying & Maintenance Guide
What to check before buying
When inspecting a used 2018 Husqvarna TC 50 with its 49 cc cross / motocross, start with the basics: check the service book for oil change frequency, inspect the drivetrain for wear, and look for oil seepage around the engine casings and rocker covers. This model runs chain final drive, so check chain slack and sprocket tooth profile specifically - a worn sprocket is a cheaper fix now than after it's chewed up the next chain. Now 8 years old, this cross / motocross is as likely to show age-related wear (perished rubber, seized fasteners, degraded seals) as mileage-related wear. A cold start test is invaluable - a well-maintained TC 50 should fire up cleanly and settle to a smooth idle within a few seconds.
Oil and filter changes
Regular oil changes are the single most important maintenance task for the TC 50's 49 cc single cylinder, two-stroke. Stick to the manufacturer's interval - typically every 6,000 km or once a year, whichever comes first. The sump holds 0.90 litres, so budget for that volume of quality motorcycle-specific engine oil. Always use the correct viscosity grade as specified in the owner's manual.
Fuel system care
The TC 50's fuel injection system is durable but benefits from quality fuel and the occasional use of a fuel-system cleaner additive. If the bike has been stored for more than three months, drain and replace the fuel to prevent varnish deposits in the injectors.
