Just my opinion -
I've had a lot of different bikes over the years but my current ride is a modified 1989 Honda GB500.
It's obviously not as fast as my Hayabusa or VMax was but it will do the 1/4 in the 12s and still idle through town.
It's light weight and good basic design makes it a fun bike to ride.
It get's 60 miles to a gallon and a lot of favorable comments from riders and non riders everywhere I go.
Most people will agree that the GB is one of the best looking bikes ever made.
Cyclewizard is currently building two modified GB662 engines ( stock stroke and 106mm bore ) for me.
One is going in a stock appearing GB
and the other is being used for a scrambler version of the GB.
Performance of both bikes will be much better than the Cycle World GB500 project
CW and I are seriously thinking of doing a production run of 10 modified GBs.
