Detailed description

Driving modes S1000RR/R/XR (K4x)

  • RAIN: optimized for wet asphalt and rain tires - very strong rider assistance
  • SPORT/ROAD: optimized for dry or light wet asphalt and sports tires - strong rider assistance
  • RACE/DYNAMIC: optimized for dry asphalt and sports tires - medium rider assistance (design mode)
  • SLICK/DYNAMIC PRO: optimized for dry asphalt and sports tires - low rider assistance
  • USER: still available; not available after activation of RCK

For sure DTC +/- level switch is active in all rider modes!

Tractioncontrol (DTC) with cylinder supression (CUTs), (K4x)

Improved in V2021!
Electronic like in WSBK on stock control unit (ECU)!

  • Traction control and Wheeliecontrol operating via defined cylinder suppression
  • The operating range of the traction control become audible to the rider
  • Faster traction control operation (compared to conventional throttle valve DTC)

Gear dependent traction control (DTC)

Improved in V2021!

  • Programming of a gear dependent traction control
  • Very intense action in 1st gear to prevent wheelies
  • Decreasing intensity by ratio difference to other gears for acceleration optimum

Wheeliecontrol (not for BMS-K ECU)

Improved in V2021!

  • Short cuts limit Wheelie (strength can be adjusted via the rider mode)
  • No Wheelie intervention in gears >= 4th to prevent torque reduction on bumpy straits
  • No jerky torque increase when the front wheel hits the track after wheelie
  • Gear and rider mode dependent power/trottle limitation for reduced wheelie tendency

Injection & Ignition (K4x)

  • Optimized torque curve for race exhaust systems and fuel >= 98 ROZ
    In "S" Stock-variant for stock exhaust systems, standard fuel is possible, >=95 ROZ recommended.
  • Softer throttle response and power delivery through full partial load optimization
  • Power increase from 3 to 7PS* possible (depending on bike hardware)
  • Torque increase from 2 to 5Nm* possible (depending on bike hardware)

Engine speed limiter

  • Programming a soft start of limiter action by cylinder blank out
  • Reduced risk of bike nervousness while reaching limiter speed
  • Slight Increase of engine speed limit up to 500rpm, because "soft limiter" prevents from over-rev

Engine brake

  • Fired config (injection continues) leads to a smoother first pickup during transfer from braking (0% throttle) to acceleration and a more stable behavior in fast corners

e-Gas, S1000 (Race Map + RR Power Map)

  • Ready for short twist grips ≥54° (not available for BMS-K ECU)
  • Programming of same E-GAS setup - according to twist grip and engine rpm - in all riding modes
  • same - race track optimized - throttle response in all riding modes
  • max. torque and power is also available in "RAIN" (max. 60% throttle in stock ECU)
  • Remove any existing gear-dependent restrictions

Launch control (L-Con) and Pitlane Limiter

  • New in V2021: Automatic Launch control engage during still stand in 1st gear for S1000RR 2019+
  • Activation and pre-set of Launch Control and Pitlane Limiter
  • Activation of more then 3 starts in sequal
  • Activation of launch control also in 2nd gear
  • S1000RR 2019+: Launch Control and PitLimiter only available in conjunction with "rider modes pro"

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 flaps (in S-variant)

  • Acoustic flap always open while riding, stock behavior in idle speed
  • Optimized Sound and torque during lower and mid rpm range
  • Better audibility of the bike while braking through open exhaust flap
  • Intake flap (e.g. at S1000RR 2019, K67) always open

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

  • Exhaust flaps and servos can be removed
  • O2 Sensors 
    (from 2019: Broadband sensor before CAT must remain, after CAT can be removed)
  • knock control sensors can be removed
  • secondary air system can be removed
  • radiator fan can be removed (function stays enabled as long as connected)
  • 2017+: fuel tank venting valve including activated carbon filter can be removed
  • 2019+: intake flap always open and removable without MIL (always remains open when plugged in)
  • 2019+: CAT heating inactive (no increase of idle speed in cold start conditions)

Individual requirements possible at an additional cost, for example ...

  • Set engine speed limitation to individual value
  • Adjust traction control to individual data (e.g. allow unusually high slip values)
  • Stronger / weaker wheeliecontrol in individual rider modes
  • Noise reduction through more closed acoustic flap and/or a later opening
  • Program tire radii of a preferred type exactly in ECU
  • Fine tuning on your own bike on our test bench
  • Modification of engine configuration (camshafts, pistons, ...) requires advance tuning of fueling and ignition --> Test bench tuning recommended
