Chassis: At the heart of the Krämer APX-350 MA is a chromium-molybdenum steel trellis frame that has been tuned for the ideal flex and feedback necessary for road racing. The chassis design has the ability to be adjusted at the headstock angle, triple-clamp offset, swingarm angle, seat height, rearset height, and handlebar angle, making it ideal for different riding styles and riders of differing sizes.

Fuel Cell: Built from cross-linked polyethylene, the 12-liter fuel cell is created using a rotational molding process, which results in a lightweight and durable design. A staple of Krämer ingenuity, a cutout is made in the fuel cell for easy access to suspension settings on the rear shock — one of many race-focused designs on the APX platform.

Engine: The Krämer APX-350 MA features a 350cc single-cylinder engine from the KTM EXC-F enduro motorcycle. Mated to a giant sealed airbox that has been optimized for maximum airflow to an oversized throttle body, peak power for the APX-350 MA will be a class-leading 55hp, before taking into account the ram-air effect on the intake. This power will be transmitted through a six-speed gearbox.

Ride-by-Wire: Throttle control on the APX-350 MA is fully digital, with a ride-by-wire system developed by Krämer Motorcycles in cooperation with Mectronik. This allows for robust engine braking control parameters, adjustable throttle maps, as well as precise ignition control for the up/down quickshifter.

Race ECU: The Krämer APX-350 MA features the Mectronik MKE7 race ECU, which should be a familiar sight for any hardcore race team. The APX-350 MA will ship with an engine calibration for VP Racing’s MGP-R Reg fuel (the spec fuel of MotoAmerica).

Data Ready: Owing to its race-built design, the Krämer APX-350 MA comes pre-wired for potentiometers that can be installed on the front and rear suspension, and is ready to use a number of data-logging solutions. The TFT dash from ECUMASTER displays key bike information and features an integrated GPS-powered lap timer.

Components: The Krämer APX-350 MA will come with premium components from WP Suspension for the forks and shock, a single front disk setup with a Brembo Stylema caliper, and Dunlop race slicks on lightweight 17” cast aluminum wheels.

Bodywork: The fiberglass bodywork on the APX-350 MA is extremely lightweight, but does not sacrifice durability. All mounting and high-stress points are reinforced with a carbon/aramid fiber composite. The front air intake is designed to help the engine breathe efficiently all the way to max revs.
