2016 KTM 450 SX-F Review
Introduction KTM 450 SX-F; redesigned in 2016, the newly crowned king SUPERCROSS. These clever Austrians not satisfied simply to adjust the 2015 model, instead of using more of a method on the ground, it seems that it has been developed a good decision.
Design - specially constructed bike like this, so necessary to limit to a certain extent by the function. Design parameters are very mature, so how would you do to build a better mousetrap? KTM's answer is to make it lighter, so they sent in 2015 to a fat camp and trim just under eight pounds of hair close combat weight 224.6 pounds, plus fuel. Line taper down to the back of the fuel tank is almost no, leaving the bicycle with a very narrow waist. This is a double-edged sword; although it has enough space to move around, leaving the riders little thin bucket hanging in their legs. Obviously, this is not for people like Ryan Dungey problem, but it may be uncomfortable experience fewer riders.
Chassis - KTM started from ground lightning project. The new framework is flexible in all the right places, stiff in all other less energy transfer from the track to the driver. Rubber install handlebar absorbs more energy, shaken by the shock and vibration, helping the rider to save energy for the important things. Steering geometry close small (0.4 degrees), rake adjustment, some additional flexibility to shorten the wheelbase 0.393 inch; the move, according to riders, can help KTM corner, even better than before.
To keep unsprung weight down factories and aluminum rocker (250 downwards g) and machining the rim and made of lightweight aluminum connecting hub laces and spoke nipples. Hoop Dunlop offered their Geomax MX32 racing tires.
WP suspension components provided by 48 mm inverted front fork and mounted monoshock. 11.8 inches of travel at both ends of the float, and is equipped with a preload and compression / rebound damping usual arrangements. Specific adjustments for the MX racing fork with a swept area fender protection fork tube.
As usual, Brembo provides bindage round ends. In vernier caliper pinch 260 mm rear brake discs in front and 220 mm brake disc, wave patterns on whether to save weight and provide better cooling effect; another area, KTM trim a little fat.
Transmission - not even the engine is sacred; newly designed mill uses a full four pounds lighter than its predecessor. To achieve this goal, the plant lopped 6 mm closed length of the cylinder, and 350 g reduce the head. The case of the engine to lose some weight, even the starter and battery were re-designed to make it as light as possible and still get the job done.
Over a million mill replaces 449.9 ml, and crank out 62 ponies, max. 63.4 2mm shorter stroke to keep the engine low vibration, and engine balancer takes care of the rest of a significantly smoother end. Water cooled, radiator tucked behind the fairing, the two protect it, but can also be used as a plunger spoon. Airbox cover the left back only to protect it becomes choked, but also to change the track fast filter. A 44 mm Keihin throttle body under the control of the engine control unit (ECU), which provides a map of the three pre-programmed different power supply curve engine Press the button to access the management engine. It also comes with a Launch Control function, the start of the speed limit, and gradually make the full power to help prevent loss of traction in the first critical seconds of the game.
Damping steel diaphragm (DDS) Clutch Couples engine power for the five-speed tranny, and with design, concise, easier to pull the clutch benefits. Bottom and top gear with a treatment plant for greater reliability.
