Detailed description

Injection & Ignition (K83/K84)

  • Optimized engine performance in part and full throttle operation
  • Power increase up to 6PS (~6%) possible
  • Torque increase up to 6Nm (~7%) possible

Dyno diagram example (values measured on wheel) with stock exhaust: F900R 2020

Engine speed limiter (K83/K84)

  • The rev limiter raised by ~ 700 revs makes the power of the F900 engine usable at high revs for overtaking maneuvers and sporty riding
  • Programming a soft start of limiter action by cylinder blank out reduces risk of bike nervousness while reaching limiter speed

e-Gas (K83/K84)

  • All modes: softer throttle response / improved behavior when applying throttle
  • RAIN: medium and high load range remains OEM
  • ROAD: slightly more direct throttle response than OEM
  • DYNA/DIRT: sporty direct throttle response

Shift assistant (SASS), quick shifter

Improved in V2021!

  • Faster upshifts (mainly in high rpm) through reduction of ignition cuts
  • More dynamic downshifts through increased throttle punch in low and mid rpm range
  • Increase of diagnostics tolerances to prevent safety shutdown during usage of race shifter (e.g. MCT-Lohmann)

Exhaust acoustics (K83/K84)

Enabling of exhaust burble in DYNAMIC and DYNAMIC PRO

Audio samples: RAIN/ROAD (without exhaust burble) | DYNAMIC/DYNAMIC PRO (with exhaust burble)

Prepared for common F900 race conversions (only in "R" version)

  • O2 Sensors 
    Broadband sensor before CAT must remain, after CAT can be removed)
  • radiator fan can be removed (function stays enabled as long as connected)
  • Fuel tank venting valve including activated carbon filter can be removed
  • CAT heating inactive (no increase of idle speed after engine start)
