Setting the bar in the ultra-competitive 85cc class, the TC 85 features much of the same technology found in the successful full-size Husqvarna motocross line-up. With a Chromium Molybdenum steel frame and state of the art WP suspension, young mini riders can focus on performance with total confidence. Featuring an engine that delivers a broad and controllable power delivery the TC 85 offers top-level performance and durability for the stars of tomorrow.
The professionally crafted Chromium Molybdenum steel frame is constructed using hydro formed tubes joined by precision robot welding to ensure the highest level of consistent quality.
The frame employs a geometry aimed at tailoring flex characteristics for optimal handling and comfort. Together with the laterally-mounted cylinder head mountings the result is advanced torsional rigidity and longitudinal stiffness. This allows the frame to move in harmony with the suspension soaking up big hits while delivering optimal agility and high-speed stability.
Additionally, the frame is fitted with “no dirt” footpegs that prevent the build-up of dirt collected through deep ruts and muddy terrain. The simple but effective self-cleaning system ensures the footpegs return to their original position providing complete control in all conditions.
The frame is finished off in a highly durable blue powder coating with standard frame protectors.
Made from lightweight aluminium, the subframe features a short and compact profile contributing to mass centralisation and the overall light weight.
Manufactured using a gravity die-cast production process, the one-piece aluminium swingarm offers exceptional strength at the lowest possible weight. For easy maintenance, the chain adjustment markings are visible from above, making adjustment simple.
Mirroring the latest technology found in the Husqvarna full-size motocross range, the TC 85 features WP XACT suspension.
Up front, the WP XACT fork with AER technology consists of a 43mm split fork design using a capsuled air spring in the left leg and the trusted oil damping system in the right leg. The components offer optimal suspension performance with 280 mm total wheel travel. Additionally, adjustment is made simple thanks to the single air pressure valve and supplied air pump for preload and easy access clickers for compression and rebound.
On the rear, the TC 85 is fitted with a specific version of the WP XACT PDS shock absorber. The design offers optimal progression and response. Wheel travel is 305 mm in total. The WP XACT PDS is fully adjustable for preload, compression and rebound.
Handlebar, grips, throttle
The TC 85 features a lightweight and strong tapered aluminium handlebar that is fitted with an advanced throttle assembly for easy free play adjustment. Additionally, the TC 85 is fitted with ODI lock on grips as standard. The system includes a vulcanised grip on the right side while the lock-on grip on the left does not require glue or wire for mounting.
The TC 85 features progressive bodywork which precisely fits the proportions of an 85cc rider. The contact points and feeling allow the younger riders to feel the similar control and comfort found on the larger models.
The ergonomics instill confidence while leaving room for free and unrestricted movement thanks to the broad and flat seat and one-piece airbox covers.
The radiators are designed using CFD (Computational Fluid Dynamics) to ensure the ideal passage of air through the cooling fins. Combined with an advanced routing of the coolant circuit, the system ensures optimum engine temperature for the highest performance in varying conditions.
The radiator protectors not only serve as protection from flying rocks and debris but also serve as a brace diverting energy around the radiators in the event of an impact.
The airbox is designed to offer the best possible performance with the highest level of filter protection.
The air filter is easily accessed, without tools, by removing the left side panel. Easy maintenance is guaranteed by the Twin Air filter and filter cage design that features a simple fail-proof mounting system for safe and accurate filter installation.
Wheels and tyres
Black aluminium rims and CNC-machined hubs are fitted with Maxxis tyres that deliver outstanding performance on a wide variety of terrain. The pattern design and rubber compound offer exceptional straight-line stability and excellent traction and predictability.
A Formula four-piston brake calliper and 240 mm wave disc at the front and a two-piston calliper and 210 mm wave disc at the rear ensure powerful and confident braking.
The piston size on the rear calliper, in combination with the precisely designed rear brake lever, delivers optimal modulation and feeling.
The exhaust system is perfectly tailored to the engine’s power characteristics, contributing to the outstanding performance and all-round ride-ability.
The header pipe is made in a three-dimensional stamping process. Once the components are shaped they are robot welded to ensure the highest level of quality and durability.
The TC 85 engine uses the latest technology to deliver unrivalled performance in the ultra-competitive 85cc class.
The engine delivers optimal performance and ride-ability across the full RPM range. Key to the engine is a power valve, which allows the power delivery to be tailored simply and effectively.
Cylinder and piston
The cylinder is designed around the power valve system. The system controls both the exhaust valve and the sub exhaust port for optimal power, torque and controllability. As a result, the TC 85 delivers class-leading mid-range performance reducing the need to use the clutch in loamy or sandy conditions.
An adjuster screw allows the opening time of the power valve to be adjusted to suit rider preference and track conditions. By changing between different power valve springs – available in the Husqvarna Accessories catalogue – the rate at which the power valve opens can be further tailored.
The lightweight crankshaft features optimal balancing for minimal vibration and the precisely tailored rotational inertia of the crankshaft improves torque and ride-ability.
The crankcases are manufactured using a high-pressure die-cast production process that keeps wall thickness to a minimum while retaining strength and durability. The design of the cases is compact and aims at positioning the shaft arrangements as close as possible to the centre of gravity for optimal handling.
The TC 85 features a lightweight gearbox with motocross-specific ratios and the progressive shifting action allows the rider to select the next gear with confidence. Additionally, similar to the footpeg design, a self-cleaning gear selector prevents the build-up of dirt ensuring complete control in all conditions.
The TC 85 features a compact and durable diaphragm spring clutch. The clutch is actuated via a Formula hydraulic system meaning that play is always adjusted, and the clutch point remains the same under different conditions and over time.
