Driving modes S1000RR/R/XR (K4x)

Improved in V2023 for RR before 2015 and HP4!

  • Function overview charts: S1000RR 2010-14, HP4, S1000RR 2015-2018, S1000R 2014-2020, S1000XR 2015-2019
  • 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 if bike is equipped with this feature!

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

Improved in V2023!

  • Completely revised traction control (compared to series) for improved drivability and reduced tire wear
  • Traction control and wheelie control work via defined cylinder surpression
  • Traction control operating range becomes audible to the rider
  • Softer and faster traction intervention (compared to conventional throttle DTC)

Gear dependent traction control (DTC)

Improved in V2023!

  • Very intense action in 1st gear to prevent wheelies
  • Decreasing intensity by ratio difference to other gears for acceleration optimum
  • Reduced susceptibility to faults due to improved diagnostics


Improved in V2023!

  • Short cuts limit Wheelie to support rider
  • Intervention strength adjustable or disabling possible via driving mode 
  • No wheelie intervention in gears > 4th to prevent torque reduction on bumpy straits (not for RR before 2015 and HP4)
  • No jerky torque increase when the front wheel hits the track after wheelie
  • Gear and riding mode dependent power/trottle limitation for reduced wheelie tendency (not for RR before 2015 and HP4)

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.
  • Full partial load optimization for smoother throttle response, optimal power delivery and reduced constant drive jerking
  • Power increase from 3 to 7HP 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 Mapping)

  • Ready for short twist grips ≥54° (not available for BMS-KP 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

Improved in V2023!

  • 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
  • Automatic Launch control engage during still stand in 1st gear for S1000RR 2019+ and S1000R 2021
  • S1000XR 2020+: Launch Control and PitLimiter not available

Shift assistant (pro) / quick shifter / blipper

Improved in V2023 for R12x0, F900, S1000RR!

  • Optimized shift assistant for more dynamic and smooth gear changes
  • Increase of diagnostics tolerances to prevent safety shutdown during usage of race shifter (e.g. MCT-Lohmann)
  • Precondition: only valid if bike is equipped with "shift assistant" or "shift assitant pro"

Acoustics: Exhaust and intake 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
  • K6x models: intake flap always open
  • K6x models: No catalytic converter heating / no increased idling after engine start
  • K63/K69 models: Exhaust burble enabled in DYNAMIC PRO (all gears)

Prepared for common race conversions ("C" and "R" variant)

  • 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 after engine start)

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
