Xornr89 again !

Okays, really i need help on this one...
What does this mean?

"Not ride motorcycles with an engine capacity over 660ml and a power-to-weight ratio over 150kw/tonne and has not been approved by the RTA and shown on the Approved motorcycles for novice riders list."

That is like the kinda bike that i have to ride, since i am still learners. Can anyone explain in like simple english... I don't under stand these motorbike terms like power to weight ratio and stuff.

Thanks in advance!

660 ml is the same as 660 cc.
150 kW/tonnes is just figuring out how much power your bike has and dividing it by the weight.
Usually over on this side of the pond we use Horsepower, but what you can do is...
A couple of ways to do it.
Easiest I can think of is if your bike has a better power/weight ratio than 0.075 kg/tonne, then you can't ride it, plain and simple.
To find out, take the power of your bike in kW, then divide it by it's weight in kg. If the number is smaller than 0.075, you're golden!

Oh, and if you would, do me a favor and edit the title of your post, fairly offensive to me. I'm straight, but have a lot of gay/lesbian friends, thanks, Wrider

1 kW = 1.341 bhp

150 kW * 1.341 bhp/kW = 201 bhp

You are allowed 201 bhp per 1000kg, so that is 0.20 bhp per kg.

I rounded down, to two significant figures.

So, find the weight of your bike in kg, multiply by 0.20 (bhp/kg), and don't ride anything that exceeds the bhp of the number you just calculated.


For comparison:


Honda Nighthawk 250,

150kg mltiplied by 0.20 bhp/kg = 30 bhp. You can't ride this if it makes over 30 bhp. It makes less, so you are ok.



Yamaha V-Star 650 Classic

229kg multiplied by 0.20 bhp/kg = 45 bhp. The V-star makes 40 bhp from my limited info, so again you are fine.

Any 600 cc racebike makes over 100 bhp and weights about 180 kg. For homework, please calculate the power to weight ratio of a Honda CBR600RR. Extra credit will be given for not actually posting your answer.


Try this "dog" out. All listed bikes should be OK.
