There were 3 base models of Suzuki RG500 production bikes through the years. The MK1 till 6 based on the XR14, the RGB500 MK7 and 8 based on the XR22 and the last versions the MK9 and 10 based on the XR45, equipped with exhaust valves and alloy frames.
In 1985 Suzuki opted to stop producing complete RGB500's, instead supplying
Padgett's of Batley with up rated, magnesium cased, stepped RGB500
engines and their associated power valves and expansion chambers.
Padgett's would then supply complete machines using a steel frame built
by Harris Performance and based on the Suzuki Mk7/8 frame. A total
of twelve engines were supplied to the Yorkshire based company with
machines being built between 1985 and 1988.
One of the last bikes an MK14 was ridden by Darren Dixon, a Padgett's
sponsored rider to victory in the 1988 British F1 Championship.
Not only Harris made frames for the RGB500 engine also Spondon, VRP and
Nico Bakker did, they even made Delta Box frames in the last years.
