2012 Yamaha WR450F announced

Published: 14 September 2011

Yamaha’s range-topping enduro machine, the WR450F, gets a significant makeover for 2012, including a revised engine, uprated frame, new bodywork plus a raft of detail changes.

The single-cylinder, 449cc, five-valve powertrain gets a reworked fuel-injection system intended to give ’more responsive and adaptable performance’, while a new ‘bilateral’ aluminium beam frame is almost 250-size in a bid to give quicker steering and sharper handling.

To match the frame, new slimline bodywork is also claimed to be to 250-class dimensions while the overall look is refreshed with new black Excel wheel rims, Pro-Taper bars and a new headlight cowl.

A ‘Competition Kit’ will also be available for riders using the bike in closed course enduros. It comprises race-spec exhaust, including silencer and tail pipe, 13/50 sprocket set and other items.

Following its successful introduction alongside its 2011 YZ450F motocrosser, for 2012 Yamaha is also offering WR450F riders the option of buying its ‘Power Tuner’, which enables bikes fitted with the competition kit to adjust the engine mapping to suit conditions.
