2014 Yamaha YZ450F – First Look All-New, still backward.
Let’s face the facts,motorcycle mufflers, Yamaha’s YZ450F is now an unsatisfactory rap. Blame James Stewart’s less-than-stellar results on the bike in 2012 well before his leap to Suzuki,motorcycle stands, coordinated with slanderous comments on the internet forums. But what happens? The “backward” design has returned, and Yamaha’s engineers,motorcycle helmets, led by Mr. Hiroshi Ito (WR450F project leader,motorcycle fairing, too) still depend on the rearward-leaning cylinder with intake at the front end and exhaust inside the rear.Highlights of one's all-new engine include reshaped intake and exhaust ports with larger-diameter valves. The piston now has two rings rather than three. Wet-sump lubr ducati clutch covers ication is already used,motorcycle fairings, and also smaller engine lies farther forward from the frame.A superb indication that ’14 YZ is significantly more potent is considered the 20-percent-stronger clutch. The five-speed transmission features new ratios; the space brake clutch levers between second and third is closer and the jump from third to fourth is wider. A totally new gear-position sensor tells th adjustable levers e ECU to pick individually optimized maps for first through third gears.Chassis updates include an all-new frame, subframe, shock, fork settings, fuel tank with hidden filler, revised and simpler air-filter access and fresh bodywork. Next thing? Motivate it on your track considering the current class leaders (Suzuki, KTM and Honda) and watch if these changes add up to success.Front 3/4 right-side viewEngine close-upSlim body profileView full-size images in photo gallery:Off-road action shot #1 - 2014 Yama rearsets ha 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 view'>2014 Yamaha YZ450F (Blue) - studio right-side view'>2014 Yamaha YZ450F (Blue) - studio left-sid motorcycle mufflers e view'>2014 Yamaha YZ450F (Blue) - studio 3/4 front left-side view'>2014 Yamaha YZ450F (White) - studio right-side view'>2 SportBike Levers 014 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 Yam motorcycle fairing aha YZ450F - rear s motorcycle helmet uspension'>2014 Yamaha YZ450F - in-mold graphic printing'>2014 Yamaha YZ450F - slim body profile'> -->
