Cyclekart Auto Union first test drive 

Most cyclekarts worldwide are limited to 17" wheels (18" for Edwardian types with artillery wheels) In the U.K. we have a limit on tyre (tire U.S) width of 3.25", the ones on mine at the moment are 2.75" but I have some 3.25" ones for the back if I don't have too much grip - which can be dangerous in a cyclekart - better to slide than to flip! Normal bicycle wheels are not good on a cyclekart as they tend to end up looking like a pringle very quickly, we use 17" motorcycle wheels from pit bikes or Honda cubs.

Thanks for the comment Dan, but the original had 16!!!

@@jimrawnsley The last one made, the type D, had a V12, so he's not necessarily wrong.

Thanks for the reply. As this is a cyclekart and therefore needs a body to be one, we do need to have somewhere to mount it. I appreciate your concern for my safety but leaving it as you suggest would mean missing out on all the fun with my cyclekart buddies... www.cyclekartsgb.com/

Yes, one of the problems I need to sort out. The lateral movement in the ARBs is too much, welded strengtheners needed. As a first test drive on a new suspension system, it was ok

Partial success @olonspeed, the steering was not heavy at all, I would say it was about right. Most cyclekarts have Pitman arm steering, mine has a rack with about three times the gearing of a Pitman arm set up. I have the same rack in my BSA three wheeler and it makes the steering a lot more predictable. I am running about 7 degrees of castor on both. steering weight difference is negligible. It goes where I point it very well :-) The lateral flex in the anti roll bars may prove excessive and I may need to weld in some lateral support before I am happy with it. I am taking it to a kart track with my cyclkarting buddies this weekend...

@@jimrawnsley Thanks for the update. Changes are inevitable in a new design, a few more upgrades and I am certain you will have it locked down.
