New DirtBikes: 2016 Husqvarna Two-Stroke Motocrossers

All-new TC 125 headlines a trio of 2016 Husqvarna two-stroke motocross models.

In addition to its impressive all-new line of four-stroke motocrossers Husqvarna has stepped up its game in the two-stroke motocross ranks by introducing an all-new TC 125 two-stroke motocross model for 2016, marking the first time in years that a Husqvarna two-stroke motocross bike has received an all-new engine design.

The TC 125’s two-stroke engine is significantly smaller and lighter than the MY2015 engine, and it boasts completely redesigned and repackaged internals, a new power valve and a new exhaust system that combine for a claimed total of 40 crankshaft horsepower, two more than the previous model. The new engine is not only more powerful, it’s also 4.62 lbs. lighter, now weighing 37.84 lbs.

Starting from the stop, the TC 125’s new cylinder features a 54mm bore with revised ports and a new power valve that is designed to improve power delivery throughout the rev range. The cylinder also sports a redesigned water jacket for improved cooling. The piston is also new, having been redesigned to match the new cylinder. The exhaust system has been completely redesigned in order to match the new engine’s intended power character and the new chassis packaging.

The TC 125 also gets a new crankshaft that is lighter and balanced differently than the previous generation in order to quell unwanted engine vibration. The crank now sits 37mm higher within the cases in an effort to improve mass centralization.

Speaking of the cases, the TC 125’s are completely redesigned, just like its four-stroke stablemates, with mass centralization and weight reduction being two important goals. All the major components have been repositioned; in addition to the higher crankshaft, the clutch shaft has been raised by 27mm. The cases themselves are made using a high-pressure die cast production process that keeps the overall weight to a minimum by delivering a thin case wall thickness. The historical Husqvarna logo adorns the bronze finished crankcase covers. One more interesting fact is that the engine cases are machined to accept an accessory electric starter that is available through Husky Power.

The TC 125’s six-speed gearbox uses the same ratios as the 2015 model, but the design is all-new, resulting in a transmission group that is 200 grams lighter and 6mm narrower. The gear shift lever also features a new tip design that is claimed to prevent dirt buildup. Power is fed to the transmission via a Magura hydraulic clutch that is claimed to guarantee excellent modulation and clutch action.

2016 Husqvarna TC 250

Husqvarna’s quarter-liter two-stroke gets minor detail changes for 2016, including a new CNC triple clamp with rubber damping and a new seat cover. Husqvarna has also fitted the TC 250 with new Brembo disc brakes and the 100-gram lighter spokes to reduce unsprung weight. A handlebar-mounted map switch, polyamide rear subframe and hydraulic clutch are all standard fare. The standard handlebar map switch allows riders to alter ignition and modify power delivery according to track layout and conditions.

The TC’s two-stroke engine features an exhaust power valve to boost power and torque along the entire rev range. That power runs through a hydraulically activated A DDS (damped diaphragm steel) clutch system, which uses a diaphragm spring instead of coil springs. The transmission is a five-speed. Husqvarna’s factory aftermarket accessory division, Husky Power, also offers a 300cc power-up kit for TC 250 owners looking for even more power and torque than the stock 250 delivers.

2016 Husqvarna TC 85

The 2916 TC 85 receives the fewest changes in the Husqvarna motocross line for 2016, making do with the new colors and graphics that adorn the rest of the motocross family. But no matter, as the littlest Husqvarna motocrosser still delivers the goods with its powerful high-performance two-stroke engine, which features a power valve to maximize the powerband. A Formula hydraulic clutch delivers power from the TC 85’s crank to its six-speed transmission

The TC 85 features a chromoly steel frame and lightweight aluminium rear subframe along with high-quality WP suspension that includes a fully adjustable 43 mm upside down fork with 10.6 inches of travel. Outback, the PDS rear suspension features complete adjustability to allow it to be set up for rider preference and track conditions. Black Excel rims and CNC-machined hubs are shod with Maxxis tires on the TC 85. Braking duties are handled by a Formula four-piston brake caliper and 220mm wave disc up front and a two-piston caliper and 210mm wave disc out back.
