2014 Yamaha YZ450F – First Look All-New, still backward.
Let’s admit it, Yamaha’s YZ450F has brought an undesirable rap. Blame James Stewart’s less-than-stellar results to the bike in 2012 previous to his leap to Suzuki, in addition to slanderous comments online forums. But do you know what? The “backward” design has returned, and Yamaha’s engineers, led by Mr. Hiroshi Ito (WR450F project leader, too) still depend on the rearward-leaning cylinder with intake at the front end and exhaust along the rear.Highlights of the all-new engine include reshaped int motorcycle rear stand ake and exhaust ports with larger-diameter valves. The piston presently has two rings and not three. Wet-sump lubrication is used, and also smaller engine is determined farther forward in your frame.A good indication of the fact that ’14 YZ is significantly more robust is considered the 20-percent-stronger clutch. The five-speed transmission features new ratios; the gap between second and third is closer as the jump from third to fourth is wider. A whole new gear-position sensor tells the eu to decide on individually optimized maps for first through third gears.Chassis updates include an all-new frame, subframe, shock, fork settings,adjustable handles,SportBike Levers, fuel tank with hidden filler, revised and simpler air-filter access and fresh bodywork. Alternative? Buy it in the track when using the current class leaders (Suzuki, KTM and Honda) and determine if these changes mean success.Front 3/4 right-side viewEngine close-upSlim body profileView full-size images in photo gallery:Off-road action shot #1 - 2014 Yamaha YZ450F'>Off-road action shot #2 - 2014 Yamaha YZ450F'>Off-road action shot #3 - 2014 Yamaha YZ450F'>Off-road action shot #4 - 2014 Yamaha YZ450F'>Off-road action shot #5 - 2014 Yamaha YZ450F'>2014 Yamaha YZ450F (Blue) - studio 3/4 front right-side rearsets view'>2014 Yamaha YZ450F (Bl ducati clutch covers ue) - stud SportBike Levers io right-side view'>2014 Yamaha YZ450F (Blue) - studio left-side view'>2014 Yamaha YZ450F (Blue) - studio 3/4 front left-side view'>2014 Yamaha YZ450F (White) - studio right-side view'>2014 Yamaha YZ450F - front suspension/larger axle'>2014 Yamaha YZ450F - hand motorcycle helmet le crown damper'>2014 Yamaha YZ450F - easy- motorcycle fairing access air cleaner'>2014 Yamaha YZ450F - frame'>2 rear motorcycle stand 014 Yamaha YZ450F - engine'>2014 Yamaha YZ4 adjustable levers 50F - rear suspension'>2014 Yamaha YZ450F - in-mold graphic printing'>2014 Yamaha YZ450F - slim body profile'> -->
