Husky’s signature red cylinder head isn’t just for show. Red Head is actually the naming convention for the dual overhead cam design that was introduced in 2012. The Red Head is employed on all 250/310 engines and uses a finger-follower valve-train instead of shim-and-bucket. It also has new cams with longer valve lift and larger-diameter valves. Bikes with the Red Head package are labeled with an “R.” Additionally, all 250/310 machines get a lightweight F1-inspired piston, new cylinder and Keihin fuel injection.
Motocross bikes include the TC250R and TC449 4-stroke models. Both get titanium valves while the 250R has beefed up radiators and a magnetic oil plug. It also dropped the hot-start lever now that it has Keihin EFI. The big-bore is unchanged except for the model-wide updates. Racers who prefer mixing their gas and oil can get two bikes in one. The CR125 comes with a 144cc top-end kit – a nice option for larger riders or anyone needing a rebuild.
Four-stroke Cross-Country riders can utilize the TXC250R and TXC310R. These machines have a claimed boost in power courtesy of a revised velocity stack and new exhaust. They also get a new ECU map for more aggressive power and the suspension is reworked, including USA-developed settings for the 48mm Kayaba fork. Reinforced radiators help with durability as does a magnetic oil plug. The 2-stroke crowd has three models to shred with: WR125, WR250 and WR300. They get the shared changes and the 125 also comes with a 144cc top-end kit.
Riders who need to link trails should inspect the dual sport lineup. The TE310R gets the same velocity stack and exhaust upgrades as the TXC models and the Red Head arrangement. The 350R joins its larger siblings, the TE440 and TE511, with more compact handlebar switches, redesigned fuel catch canister and DOT tires that are said to provide better off-road traction.
