We’ve run both models of new GSX-R now – the standard and the R – and they share a giant EURO4 exhaust end-can, which is horrendously restrictive. Obviously on looks alone they’re headed for the skip but this is also a good thing because it is holding the engine back.
We’ve just ECU remapped a bike with a full Arrow system and the power difference is massive; from 185bhp stock to near 200bhp… YOWZAHS! Now we all like more power but if you’re tempted to bung a can or system on without a remap you’ll soon find out how much the fuelling needs changing. But also the EURO4 emissions controls need dealing with, as the engine is heavily managed.
It’s got a lovely bottom end, and midrange too thanks to the variable valve timing and the delivery is smooth and linear – beautiful. It’s just stifled at the top. But not by the time it’s been through our workshop and on our Dyno.

That can’s gotta go!
You wait for a GSX-R1000L7 to come along then two arrive together…
