Building a race bike from scratch
Building an MZ race bike is so easy, even I managed it. When a mate told me he was interested in racing, I decided to try building a bike for him out of my spares. The main part I was missing was a frame. MZ tuner Tony Holmshaw, from March, Cambs, has loads of scrapped bikes and I bought one from him for £15.
I hacksawed off any parts that weren’t needed, like the battery box, a few brackets and the centrestand, then gave it a new coat of paint. I bashed out the knackered old head bearings and splashed out £15 for two new ones. I had a spare set of forks and yokes and getting the seals changed cost £30. After a bit of fiddling, I wrestled the swingarm into the frame, then slotted my spare wheels in with the aid of secondhand spindles. The seat unit simply bolts on and so does the tank. Clip-ons (£25) also have to be fitted – before the forks go in, as I discovered afterwards.
I have no idea about engines so I gave my tuned unit to Holmshaw to put together. This cost me £50. The engine is held in with two bolts at the back and one on the cylinder head – simple.
I had a spare brake system, a twistgrip was £10 and getting a carb bored was £25. My dad made the rearsets and the footpegs cost £20.
If you fancy a winter project, scan through MCN BikeMart or dig through the local scrapyard. Parts can be bought from Holmshaw (01354-656345) or Burwins (020-7359-3050).
