The Krämer EVO2-690R starts with the same race-ready components as the S plus an upgraded 80hp KTM 690 LC4 engine, a superior braking package and forged wheels.
Frame: The Chromium-Molybdenum steel frame at the core of the Krämer EVO2-690R is responsible for the handling and durability of these motorcycles. This superior material outperforms aluminum and is much less susceptible to cracking or breaking under the stresses of racing. The unique trellis design provides great stiffness, yet flexes where it is needed, and gives the rider unmatched feedback.
Tail section: The tail section of the EVO2 is made of XPE plastic and works to support the rider and house 3.17 gallons of fuel. With this multi-use approach reduces weight and makes for a more compact package.
Body work: The fiberglass body work on the EVO2-690R is extremely lightweight, with carbon/kevlar reinforcement. And by replacing the traditional gas tank with the airbox, the bike’s overall weight reduced, weight distribution is improved and the center of gravity is optimal for the track.
Suspension: For 2020 the front suspension of the R spec has new WP Super Sport forks. These forks are pressurized, closed chamber design, featuring adjustable preload, compression, and rebound damping. The rear has a WP shock absorber with KMC Link System and adjustable ride height. When combined with a very stiff, all-aluminum swing arm, the result is a very tunable and predictable setup for dialing in your Krämer EVO2-690R.
Brakes: The R model is fitted with twin 290mm rotors and twin Brembo caliper. Rear brakes for both EVO2 models feature a 220mm Motomaster rotor and Formula caliper.
Engine: The KTM LC4 has a completely reworked the cylinder head, new, ultra light and extremely strong piston and connection rod, rerouted the air intake through a resonator chamber. As a result, the power band is a thousand rpm wider, this provides an even more uniform power delivery, especially in the mid to high rev range. Twin ignition featuring plug-selective mapping, rock solid but featherweight internals and optimized intake and exhaust systems cultivate this massive mono to be as strong as it is smooth, assisted by an advanced ride-by-wire system, which guarantees great refinement as well as improved fuel consumption.
Cylinder head: Inside the cylinder head, the exhaust valves are actuated by roller rockers while the camshaft powers the intake valves. Therefore, the valve timings can be controlled with far greater accuracy. The result is more peak power over a broader rev range.
Second balancer shaft: The LC4 features a bonus balancer shaft that reduces the annoying vibrations typically present in large thumper.
