In straight sections
I just recently had a look at the actual test reports from our test rider Anders Andersson when he was testing the system at Karskoga Raceway and he was making stabile 1,38 and 1,39 laps and when he switched on the 2WD he started making 1,34 and even one or two 1,32,5 laps – and did I mention that it was raining like crazy at that test!
The most important benefit when using the system was actually the improved confidence the rider felt when riding really fast - the characteristics of the bike actually improved dramatically. The wet track made the front and rear wheel move sideways as the rear tyre was more or less spinning all the time.
When we used the 2WD system the rear tyre still moved sideways but the front wheel was stabile as a rock and this gave tremendous comfort to the rider.
Anders soon realized that the system also loved all curves. Thanks to the G forces the front tyre can transfer more power to the asphalt and as the rear tyre is much wider than the front tyre resulting that in a leaned down corner situation were the contact patch moves up on the tyre shoulder the rear tyre is actually moving faster than the front wheel, making the 2WD system go live, transferring power to the front tyre as if the rear tyre would be spinning.
As you can’t have too much spin on modern hypersport bikes when cornering this feature was much appreciated. To be honest we didn’t even foresee that the system would react in such a way when cornering and this bonus was added to the already very successful project.
