I've built 10 race bikes over the years and have enough parts to build a few more. Here is a list of what I've built to date; 1981 kz 550,1981 gpz 550, 1982 kz 550,1977 kz 1000,1982 kz 1000j,1978 kz 1000,1978 kz 650,1984 kz750, 2x 1978 GS 1000's.
In my inventory we could put together the following race ready bikes;
1978 KZ 650
1982 GPZ 750
1981 KZ 1000
1977 KZ 1000
1982 Suzuki GS 1100E
I also have a rolling chassis to build a 1978 GS 750.
Building a race bike is anything but inexpensive. If you have the money that it takes to build a reliable competitive race bike I have the expertise to build it.
