View Full Version : Who would I talk too to find out more info on the new learner licence rules?

Specifically I want to know if an older bike that isn't on the LAMS list of approved bikes but meets the criteria can be ridden by a learner.

I have a Honda CM400 that if it was brand new, would have 6hp to much to be approved. I'm pretty sure though that it isn't that strong any more. A friend of mine really likes it but he only has his learners.

Who would I need to talk too to find out what the rules are regarding situations like this?

How do you know it has to much hp? Its a power to weight thing and it probably weighs as much as a small house.

While googling around I came across the figures for the LAMS system. IIRC it was 150kw per tonne. I converted this figure into HP and did a bit more maths and thats how I figured it out.

I'll try to find my working out. I wrote it all down somewhere...

Quick google says they have 43hp and weigh 180 kg.

Yip. 150kw is 201.15hp. Thats 0.20hp per kg for a bike to be learner approved. It must also be under 660cc.

The CM weighs 184.0kg and has 43.32hp. This gives it 0.23hp per kg.

That means the bike has 6.5hp to many. Surely a bike this old will have lost some guts since it was new and would now fall into the learner category?

Who would I talk to to find out if my friend can ride the bike?

You can add 100kg to the weight in the equation to account for rider weight and gear, so it is LAMs legal

Thats not the calculation. I did my bike a while back and it misses out as its 59hp and 170kg. Youve missed a few steps.

Found it, 1000 (kg= 1 tonne) Divided by [the bikes weight in kgs plus a 90kg rider] x power (kw) = your killowatts per tonne.

What steps did I miss?

As far as I'm aware the riders weight doesn't come into the equation at all.

According to your method, my bike has 175kw per tonne. Although I'm not factoring in any rider weight.

You have to factor it in, thats the LAMS calculation. You cant change because you want to.

Where did you get this info from? All i can find are australian sites. Can you post up a link to a nz site? I can't find one on google.

Be aware however, that there is also talk that there will be a list, like the Australian version. If your bike isn't on it then tough bikkies.

Whether or not extras will be allowed, I'm not sure.

Mention of rider weight as part of the calculation is correct. That weight is 'averaged' at 90kg.
The old CM400 is not that common, so it may not be on the list when it finally comes to pass. But it is not impossible to have it added - just difficult.
YT's EX500 (Kawasaki twin) is compliant in Oz, so why wouldn't the CM400? It is after all, a ploddy twin cruiser.
