After being invited to this: http://www.yellowboxevents.com I decided I’d have to build something pretty decent to compete

Looking at the available materials I figured a trike was the best idea - starting with the front forks from a Kawasaki GPX250. First step was removing the headstock from the frame:

Then welding it to some 4″ tube which I can only assume was scrap truck exhaust:

A borrowed boat trailer axle provided the rear wheel setup:

after being welded to the frame tube with a nice thick steel plate in between:

With the addition of an old race seat and a foot peg, the trike was complete:

I was going to keep it “rust core”, but decided that it didn’t match the sections of blue painted steel, so it really needed a proper coat of paint:

The event itself was awesome, and the 700m long track with 100m fall was suitably fast and scary!

We had round robin heats for the first half of the day, and a full grid race for the final at the end.

I was lined up on P2, and got a bit of a slow start due to the trike’s weight. The wide rear axle makes overtaking difficult so I was a bit stuck until the leading kart snapped a wheel off and spun out and I managed to take the win!

Here’s my wrap-up video of the event:

Next year I’m going to have to build something lighter and narrower
