Tested my Rotax 125

Yesterday, Munib and I went to the USJ Elite kart circuit for a few rounds on our Rotax Max.

I can concluded 3 things:

  1. I don’t know much about karting technicals
  2. the track is very bumpy and physical (ouch!)
  3. need to improve my fitness *sigh*

The chassis is an Arrow 2004 ax5-125 chassis. Not sure whether that is correct. The handling was alright, although the bumpy USJ circuit did not help the relatively stiff chassis. A few times the bumps caused my foot to either fly off the pedals or on to it! Imagine going round one of the fast (& bumpy) corners and having the left foot accidently hit the brakes… that was a bugger moment for me.

Luckily for me, the kart was set with a bit of toe-out (1mm), thus making the kart less likely to spin under braking. Still, I felt that it made cornering a bit less compliant. Perhaps a bit more neutral toe setting. May want to experiment with a bit of toe-in as well.
