I was about to make Rich's point.
Suzuki seem to be doing a Kawasaki 10 years after Kawasaki.
The GSXR600 has had the closest thing to a ground renewal in the last 3 years. The GSXR1000 has only been tweaked since 2008 (granted with some top draw road parts). The SV is a good example, they've done one thing to the entire bike (Since the 2005 models) and thats a twin spark engine.
Well its also been Yamaha, the MT-09 is the first ground up new bike since the Crossplane R1 landed (And made similar speech to Kawasaki at the Milan show)
Honda; feck me it makes car platform sharing look simple. 1 chassis, 3 completely different focus bikes. I will say I am looking forward to seeing the new 650 twin (*cough* HRC supertwin *cough*
)
