I'm not talking about backing vocals.....so Lee Kerslake isn't relevant.
So that leaves David Byron and Ken Hensley.......but only one of those is correct!
In terms of handling, the GS750 was the best of the big bikes back in those days!
But it was a long way off being as good as the RD350. The 400/4 was decent enough, while the Suzuki and Kwak Triples were hard work.
