Kramer HKR Evo2 S – First Look

The purpose-built Kramer HKR Evo2 S track bike returns for 2023 with a reduced price tag of $15,995 and more upgrade options.

The 2023 Kramer HKR Evo2 S comes standard with everything you need to be competitive on the track. The S spec features an 80hp KTM 690cc LC4, race-focused chassis, tunable suspension, selectable engine mapping, and advanced braking systems.

The HKR Evo2 S is powered by the latest KTM LC4 690cc single-cylinder engine platform that includes a balancer shaft that reduces vibrations. To increase the power band, a high-flow cylinder head, ultralight piston, and connecting rod are employed. The high-flow intake system was designed specifically by Kramer Motorcycles to provide more uniform power delivery.

A chromium-molybdenum trellis steel frame houses the KTM LC4 690 engine. This frame configuration surpasses aluminum frames and is less liable to cracking or breaking under the intense pressure of racing circumstances. The trellis design allows for great flexibility without sacrificing rider feedback.

The front suspension uses 43mm WP forks with adjustable compression and rebound damping. The rear setup is an adjustable WP shock absorber with a KMC link system. The aluminum swingarm is rigid and underbraced for stability.

The Evo2 S features a single Brembo M50 four-piston caliper paired with a 320mm Motomaster rotor. The rear brake, on the other hand, uses a 220mm Motomaster rotor along with a super lightweight formula two-piston caliper.

The XPE plastic tail section of the Kramer HKR Evo2 S serves as the fuel tank, holding 3.17 gallons. The fuel tank is replaced with an airbox. Engineering cues like this help the Kramer maintain a fighting weight of 285 pounds.

Another factor contributing to the weight class is the fiberglass bodywork. Everything that needs to be mounted securely or could experience a lot of stress is reinforced with carbon fiber and Kevlar.

Kramer offers a selection of optional upgrades for the HKR Evo2 S that include an Andreani Drop-in Fork Upgrade Kit, an Upshift quick shifter system, an AiM MXM digital color dash, and a GPS/gyroscope datalogger. Other upgrades offered include a Dymag UP7x forged aluminum wheelset and a Brembo RCS 15 Corsa Corta master cylinder, Brembo brake pads, and BrakeTech steel rotor upgrade kit.

“The Kramer HKR Evo2 R will always be our ‘no compromises’ turnkey race bike for riders who are fighting for race wins and championship victories. But with the Kramer HKR Evo2 S, we wanted to offer a more affordable way to get on a Kramer, without sacrificing too much of the Lightweight performance that’s become associated with the Kramer name.” – Joe Karvonen, Kramer Motorcycles USA CEO.

It is important to note that the Kramer HKR Evo2 S is a race motorcycle designed only for use in competition. It cannot be used on public roads or highways and it cannot be registered as street legal. Key points of difference between the S and R models are the brakes, wheels, and suspension, while the bikes share the same chassis, engine, and bodywork.
