Honda pioneered the V4 bike, but Yamaha perfected it with the Vmax.
My V30 Magna got me set on having another V4 motorcycle. That 500cc V4 would keep up with 1700cc H-D's, and was a very quick bike....the motor redlined at 11,500 RPM as well. Not a hint of vibration at any RPM, and it always ran, well, like a Honda. Never a lick of trouble. I know the V30 was discontinued due to poor sales, it was too far in the shadow of it's big brother the V65 for anybody to really care or notice.
The Honda V-4's still have quite a following at v4hondabbs.com, I have an account there and still check in every so often.
It'll be interesting to see what Honda cooks up for a new V4- could they snatch the title for muscle cruiser back from Yamaha after 24 years? Honda did hold it originally when the V65 came out, only for a couple years though.
