For the first time a cost-effective and accurate rear wheel power and torque measurement device is now available. Designed to be a self-contained sensor unit, the rear wheel torque transducer is a direct replacement for your existing rear wheel sprocket carrier. The innovative design allows torque to be measured at the rear wheel, enabling race teams to increase their knowledge, and cost-effectively develop their motorcycles, in a way that was not possible before. BENEFITS
Provides real-time “dyno data” in real-world conditions.
Cost effective engine development. Engine power characteristics can be obtained at race weekends, minimising testing time
Direct replacement for the majority of sprocket carriers fitted to race wheels. Proven to work with BST, MFR and OZ wheels
Proven accuracy in comparison to torque transducer systems fitted to the gearbox output shaft
Cost effective alternative to torque transducer systems fitted to gearbox output shaft, plus easier to install and calibrate
Proven to reliably operate at torques as high as 1400Nm and vehicle speeds of over 230mph
Inter-changeable between wheels FEATURES
Self-contained, compact design
Measures drive torque and engine braking torque
Robust aluminium housing will accept rigours of paddock use
Lightweight integrated design minimises increase in un-sprung mass
Fully balanced assembly
Wireless output signal to chassis mounted receiver box
Internal rechargeable batteries, with long life of 10 hours
User can control the wake-up and sleep modes of the sensor to further optimise battery life
Fully sealed and waterproof electronics
High logging rates are possible up to 1000Hz
0.5V – 4.5V analogue signal output. Proven to work with 2D, Magneti Marelli and Motec data-loggers
Can be calibrated to +/- 1500Nm
