Junior Motard

[Hilli32]

hey guys just been thinking about motors and im really keen on wanting to get into motard full on. so would i be able to legally race a 143cc in the junior 140 class??? :action-smiley-003:

Dont think there is a 140cc class. under 160cc or 85cc 2stroke.

If you get bitten by the motard bug you will upgrade ASAP!

are you sure i was down at warrnambool 2 weeks back and i was riding in the 140 class and apparently that is the max capacity for juniors under 16 im 14

Yes you are right. juniors last time i read the rule book (which i cant find now) said juniors under 16yr are 140cc 4-stroke and for some reason 85cc 2 stroke.

Then that is divided into 2 with both of chinese make, and the other class of anything make.

i was the one on the black pocket bike that won the senior all in King race.

Check with Chris Jones as he is the MA representative for minimoto. The engine capacity limits are set and there is no provision for a 5% or even a 1% over capacity allowance. I can't remember off the top of my head what rule number but it is stated in the manual of motorcycle sport issed by MA each year.
I think you will find that the yx 160 is allowed as is is maketed as a 160cc engine, how ever be careful with a 143 bbk as it is known exactly what the capacity is.
I personally would be sticking to a Zongshen 140 modified with a head and piston. It won the nationals, and I would go as far to say that it would be more reliable than a big bore kit on a 125.

Found it:

Seniors - 4 stroke up to 160cc auto or manual or 2 stroke up to 85cc auto or manual (as per MA 2011 rule book 15.21.6.1)
Juniors age 9 to under 13, 4 stroke up to 125cc auto or manual or 2 stroke 85cc auto or manual (as per MA 2011 rule book 15.21.8.1)
Juniors age 13 to under 16, 4 stroke up to 140cc auto or manual or 2 stroke 85cc auto or manual (as per MA 2011 rule book 15.21.8.2)

I think juniors 9-13 should read 65cc two stroke but don't count me on it!!!
