KTM 450 EXC 2016
THE BENCHMARK

 
 

The 450 and 500 EXC models are undisputedly the most powerful Enduro machines of their classes. Combining low weight and high displacement, high-tech SOHC (single overhead camshaft) 4-stroke technology is the right choice for all riders that are looking for maximum four-stroke performance, combined with playful handling for the E2 and E3 classes. These power-houses are without a doubt the benchmarks in their classes.

Frame

     

Triple clamps

     

Suspension

   
    The modern frame design of the 450 EXC, comprising lightweight, high strength, chrome-molybdenum steel section tubes, combines maximum longitudinal stiffness with optimum torsional stiffness. It guarantees easy handling and precise steering behavior, as well as excellent ride stability. So the new frame not only shines with the new color, it also clearly represents the benchmark in terms of weight and stability. The frame color shines in the same orange as the KTM factory racing team, making the styling even more attractive. Thanks to the frame design and in conjunction with the rear PDS damping system, impacts at the rear wheel are absorbed and dissipated optimally. For MY 2016 the frame is protected by a robust frame guard.       The high-end CNC machined triple clamps have been specifically designed for enduro use and ensure precise handling thanks to their supporting of the fork flex. The rider receives precise feedback from the front wheel, even in the toughest terrain, thereby increasing riding safety and speed.       The KTM 450 EXC is fitted with a new front fork featuring newly designed fork boots with shorter offset and a new suspension setting, optimally tuned to weight and engine. In addition, the fork features new fork guards. The high-quality WP suspension components have been specially designed for enduro use. They ensure maximum traction and plenty of comfort. At the rear, a PDS shock absorber from WP Suspension works with a direct linkage to the upper side of the swingarm. The wide range of setting options for rebound damping and high- and low-speed compression damping are standard on KTM bikes.    
                         
                         
                         
                     
   

Swingarm

     

Cooling system

     

 

   
    The cast aluminum swingarm has been developed with state-of-the-art calculation and simulation software and constructed, in terms of design and wall thickness, for minimum weight with optimum stiffness and precisely defined flexibility.       The proven integrated KTM cooling system routes the coolant from the cylinder head through the frame triangle directly to the aluminum radiators made by WP. A radiator fan is standard equipment for the big displacement 450 EXC.

Graphics

     

Fuel tank

   
    The speedometer by MAE integrates all the warning and indicator lights, except the turn signals, in a single unit. This gives the cockpit a clean and minimal look, with clear and readily available information.       Completely new graphics for MY 2016 compliment the look of the Enduro bike range in style.       All fuel tanks are made of lightweight polyethene. These large capacity tanks are specifically designed for Enduro use and have a release mechanism of the ¼-turn bayonet filler cap that can be opened quickly and easily.    
                         
                         
                         
                   
   

Bodywork

     

Airbox

     

Handlebar

   
    The bodywork has been designed ergonomically and functionally in such a way that the whole motorcycle is in perfect harmony with the rider down to the very last detail.       At the same time, the ingenious design of the airbox guarantees optimum protection of the air filter from dirt plus maximum air throughput for high performance. The airbox covers are manufactured in a 2-component process with new in-mold graphics. The filter is replaced very quickly, without any tools. Furthermore, two additional tabs on the cover allow it to be secured with bolts if desired.       All EXC models are fitted with the super strong, tapered Neken handlebars made of high tensile strength aluminum alloy. The proven standard KTM mount allows the handlebar to be fixed in four different positions. A new light switch made by Leonelli is designed to fulfil the requirements of Enduro use. The open hand guards are serial equipment providing optimum protection of the rider’s hands.    
                         
     
 

Wheels and brakes

 
     
                         
                   
   

Wheels

     

Brakes

     

Front axle

   
    The black coloured 7050 T6 aluminum Giant rims with black spokes are mated to CNC machined hubs and lightweight aluminum nipples to achieve maximum stability at minimum weight. Especially developed for KTM, the OEM Maxxis Enduro tires deliver perfect traction and outstanding performance.       High-tech Brembo brakes have always been standard equipment on KTM offroad bikes, and combined with the lightweight Wave discs, they are the ultimate solution in braking technology. Being the class-leading brakes in Enduro, they are unchanged for MY 2016.       The front axle has been reduced in size from 26mm to 22mm to reduce weight and offer better front end feel. The adjusted offset and increased trail provides more stability.    
                         
                         
                         
                       
   

Front fork guards

     

 

     

 

   
    The fork protectors have been adapted to the fork shoes and are also lighter. The open design offers the same level of protection while giving easier access to the fork legs for quicker cleaning and faster maintenance.                    
                         
     
 

The 450 powerhouse

 
     
                         
                   
   

Engine

     

Cylinder head

     

Piston

   
    Developed for tough Enduro duty, the SOHC engine wtih 449.3cc is distinguished by an extremely compact design, easy maintenance and excellent durability at a minimal weight. Together with the Keihin EFI system, this provides unrivalled Enduro specific performance and rideability.       The cylinder head is equipped with a single overhead camshaft. It activates two titanium intake valves and two steel exhaust valves. The weight optimized valve train leads to low friction for improved performance as well as low engine braking action.       The lightweight, forged bridged box-type piston shares its high performance piston rings with the 450 SX-F.    
                         
                         
                         
                   
   

DDS clutch

     

Crankshaft

     

Engine management system

   
    The single-piece basket of the DDS clutch (damped diaphragm steel) is machined from solid high-tensile steel in one piece together with the primary drive gear. This process guarantees unbeatable reliability and, together with the thin steel linings, contributes to the narrow engine width due to its compact rivet-less design. The diaphragm spring makes it possible to implement an additional rubber damping system inside the clutch hub, ensuring reliability for the transmission and good traction. Finally, the hydraulic clutch mechanism by Brembo in conjunction with the diaphragm spring provides a very light operation and good controllable modulation of the clutch.       The crankshafts with strokes of 63.4mm and ultra-lightweight conrods are made by Pankl from special high-tensile strength steel. The crankshaft employs a plain big end bearing. Two force-fitted bearing shells run directly on the crank pin. The necessary oil feed for this bearing is ensured by the engine’s pressure lubrication. This design increases the engine’s long-term durability, and lengthens crankshaft service intervals, which is a customer benefit in terms of time, effort and cost.       The Engine Management System by Keihin with electronic fuel injection and a 42mm throttle body ensures a spontaneous response and maximum engine performance. An oil-cooled 196 W AC alternator provides sufficient energy for the fuel injection, lighting and other electrical loads. With an optional map-select switch from the Power Parts program, the EMS can allow the rider to select different engine characteristics. In addition, the optional User-Setting-Tool provides the facility to readout engine data with a laptop and change the ignition and injection mappings with a few mouse clicks.    
                         
                         
                         
   

STARTER

The 450 EXC is equipped with kick-starters as well as electric starter as standard. The electric starter is well protected behind the cylinder.
               
         

Counter balancer

     

Transmission

   
          In order to balance the mass-forces, the engine uses a counter balance shaft, which doubles as a water pump drive.       The proven 6-speed gearbox is distinguished by easy and precise shifting.
