2017 TC 250

2017 Husqvarna TC 250

Husqvarna has released their MY 2017 lineup. The biggest news is the all new TC250 2-stroke. 

We will continue to keep you posted as the entire Husqvarna lineup comes available. At a quick glance here are the biggest changes to the 2017 TC 250. The 2017 Husqvarna TC250 two-stroke weighs 211.2 pounds (without fuel). I think this is a couple of pounds lighter than MY2016.

• New engine

 

The 250cc 2-stroke engine is the ultimate combination of unsurpassed power and lightweight construction. The simplicity and low maintenance cost of the 2-stroke motor makes it a favourite amongst motocross riders. The new TC 250 engine has a completely new construction featuring a new shaft arrangements for better mass centralisation, a new counter balancer shaft reducing vibration, a new twin-valve controlled power valve and re-worked 5-speed gearbox.

• New Cylinder

The 66.4mm bore cylinder features a newly developed power valve system which delivers smooth and controlled power throughout the RPM range. This can be further customised by simply changing two springs supplied and altering the power delivery for different track conditions or rider preference. The new cylinder and cylinder head incorporate a new water jacket design which guarantees better heat dissipation and improved cooling under the most extreme conditions. New cylinder head mountings secure the engine to the frame while also reducing vibrations for a smooth ride.

• New crankcases

In an effort to centralize mass, the lightweight die-cast engine casings are developed to accommodate new shaft arrangements. The clutch shaft is now 4mm higher while the crankshaft position is also raised 19.5mm centralising oscillating mass and improving ride-ability. Additionally the new counter balancer shaft has been integrated in a very compact manner without compromising the overall design while new engine covers offer better resistance from wear created by riders boots.

• New frame

With years of experience in designing the most advanced steel frames in offroad, the engineers in Research and Development designed a chromium molybdenum steel frame that redefines every structural aspect that benefits handling, ergonomics and packaging. With carefully calculated tortional and longitudinal flex, the frame works in harmony with the suspension to offer sharp handling and superior comfort. These characteristics, matched to a lightweight and compact engine design, offer exceptional handling precision while at the same time increasing bump-absorption and feeling.

• Carbon fibre subframe

The use of carbon fibre strips away weight, improving weight distribution and bringing weight closer to the centre of gravity for precise handling. The composition of the material is 30% carbon fibre and the overall 3-piece construction is remarkably light but also very strong for an overall weight of 1.4 kg. Additionally, a specific rigidity has been calculated in the component for optimal handling and rider ergonomics.

• New exhaust header

• Mikuni Carburettor

MY2016 fuel system was the Keihin PWK 36S AG

• WP AER 48 suspension

 

The WP AER 48 is a new milestone in the development of Husqvarna motocross models. It is safe, lightweight and easy to adjust through a single air valve and supplied fork pump for pre-load and click adjusters for compression and rebound. The system is made up of a set of split-system forks consisting of an air suspension unit and a hydraulic damping unit. The new forks offer a weight reduction of 1.6 kg in comparison to conventional fork systems of MY16. The forks are extremely responsive thanks to friction-optimized surface coating on the outer and inner tube surfaces and optimally designed sealing systems.

* WP DCC rear suspension

The WP DCC rear shock is designed to provide advanced damping characteristics while keeping to a compact and lightweight design. With a pressure balance inside the shock, damping is consistent and results in greater rider comfort and handling. Additionally, the outer surface of the gas reservoir is corrugated and increases cooling. The component is also fully adjustable and matched to a linkage system with a specific geometry to deliver the best possible traction and progression.
