Fast Bikes magazine are currently doing their dyno runs at JHS Racing for SBOTY 2017. Interesting results as the bikes are now Euro 4 compliant.
All bikes are completely stock 2017 models apart from the Yamaha that is running an Akrapovic end can, cats still remain.
At the wheel results so far..
Aprilia RSV4 180bhp 105nm
BMW S1000RR 179bhp 108nm
Yamaha R1M 176bhp 103nm
Suzuki GSXR 1000 171bhp 103nm
Kawasaki ZX10R 170bhp 99nm
Honda Fireblade CBR1000RR SP 160bhp 98nm
Aprilia claim 205bhp at the crank whereas Honda claim 178bhp at the crank. No surprise results there, when you factor in the 12-15% loss to the rear wheel.
