2014 Yamaha YZ450F – Start looking All-New, still backward.
Let’s face the facts, Yamaha’s YZ450F is now a negative rap. Blame James Stewart’s less-than-stellar results on t double bubble windscreen he bike in 2012 well before his leap to Suzuki, blended with slanderous comments on the internet forums. But do you know what? The “backward” design is back, and Yamaha’s engineers, led by Mr. Hiroshi Ito (WR450F project leader,motorcycle mufflers, too) still confidence the rearward-leaning cylinder w led tail light assembly ith intake at the front end and exhaust in the rear.Highlights from the all-new engine include reshaped intake and exhaust ports with larger-diameter valves. The piston presenting two rings rather then three. Wet-sump lubrication is actually used, and the smaller engine is placed farther motorcycle fairing forward from the frame.A fantastic indication that your ’14 YZ is significantly better is a 20-percent-stronger clutch. The five-speed transmission features new ratios; the gap between second and brake clutch levers third is closer whilst the jump from third to fourth is wider. A completely new gear-position sensor tells the ECU to settle on individually optimized maps for first through third gears.Chassis updates feature an all-new frame, subframe, shock, fork settings, gas tank with hidden filler, revised and easier air-filter access and fresh bodywork. Alternative? Buy it to the track with all the current class leaders (Suzuki, KTM and Honda) and watch if these changes soon add up to success.Front 3/4 right-side viewEn rearsets gine 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'> adjustable levers 2014 Yamaha YZ450F (Blue) - studio 3/4 front right-side view'>2014 Yamaha Y motorcycle helmet Z450F (Blue) - studio 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 - handle crown damper'>2014 Yamaha YZ450F - easy-access air cleaner'>2014 Yamaha YZ450F - frame'>2014 Yamaha YZ450F - engine'>2014 Yamaha YZ450F - rear suspen motorcycle engine covers sion'>2014 Yamaha YZ450F - in-mold graphic printing'>2014 Yamaha YZ450F - slim body profile'> -->
