Power-to-weight ratio law and bikes

[\m/]

I'll probably be getting a 2nd generation 250 Bandit in a fews weeks, about 130kw per tonne with 90kg rider. The power/weight ratio is about the same as a stock VX SS Commodore, so it should keep me entertained till I get my full. They should bring in power limits for learner/restricted car drivers though, people can legally drive a 1000kw/tonne car on their learners if they have the money to build it.

Well according to that, given my actual weight, mine comes in at 219KW/tonne...hurhurhur........course I am NOT on a restricted licence.....

Interesting.. power to weight ratio of my bike in dry weight and at the crank is 860kw per tonne (thats a nice high figure)

Power to weight ratio of my bike in wet weight with me on it is 535kw per tonne.

Thats a huge difference. Wish i weighed nothing so i could experinece a power to weight of 860kw/tonne that would be INSANE

And if i change back to old school terms thats 1157hp per 1000kgs. WOW

[avgas]

I reckon should be 80kw a ton for learners.

Noobs are fucken stupid squids. and need to learn how to make 10kw go fast first.

This law is point less.

It will not achieve anything, even with car drivers.


How many riders do you know that are on a 250 currently and its too much power for them? Sure there are the two stroke 250's that put out a lot of power but how many realistically are out there on the roads? not many. Of that few, how many have caused a learner rider to bin? Few of the Few.

Now how many learners have crashed riding the lower power 4 strokes? Many Multitudes more. The problem is not the power, its rider training.

Now if this were to go onto car drivers / boy racers. Again how many boy racers are on the road? Not many. How many of them are driving sensibly and the power of the car causes them to crash? NONE. Crashes are random multi-factor events. I would wager that most boy racer accidents are from doing skids and driving recklessly out side of there skill base. I know, because Ive done it before. I know because I've seen lots of mates do this. I know because Ive driven with skidmark.

Is anyone naive enough to think that reducing the power reduces the ability to drive like a mad man? You should of seen me in my 1983 1.3L hondamatic. it had 2 gears, yet it still could do skids and take corners at 130km/hr.

This law is pointless, a waste of time and a huge waste of money. It dose have massive public support however. It will achieve nothing apart from the issuing of more tickets.

Having said all that. I'm a huge supporter of this law. Why? It'll drop the 250 bike prices down, I hope!

My first bike was a first gen bandit 250, awesome lil bike revved like a crazy thing (17k redline) and was a blast to throw around. Did 15,000k on her with next to no problems including heaps of open road.

My Er6n appears on the 'approved for learners' list. I guess this means that those who crowed that they and Suzuki 650's were in for a big price drop after the rego increases may well be wrong eh? I'm actually surprised that it makes the list, i'm sure I read somewhere that it has more torque than a CBR600. Seems power(aka potential danger factor in this context) is measured in peak hp output at peak revs...but realistically who rides like that everyday on the street in a 50km/h speed zone? High torque at low revs when accelerating is arguably equally dangerous for new riders isnt it surely?

if you buy into the power = bad

just like speed = killed

Load of political bs

Good thread, but ponder this. What if you have a 2 tonne Hog, weigh 150 kg and yer Hog puts out a whopping 65 bhp? Are the gummint going to give you a horsepower credit?????

[Cheesy]

hmm a 650 berg on the oz list, that would be fun around town

My current bike delivers 490kw per on its own. Load my fat arse aboard plus a full tank of gas and it drops to around 325

Hows his risk assessment abilities?

I'm not putting down the aquisition of skills but skill without judgement is a crash waiting to happen

What you talkin' bout Willis? Basic Handling skills have little to do with risk assessment. That's a completely different kettle of fish.

Sure. But they'll offset it against the carbon deficit. You still owe money. Sorry.

I'm expecting bikes with high torque/weight ratios to become quite popular once the law comes in. Example: two bikes have 150kw/tonne, but one of them has twice as much torque. Obviously the bike with more torque will be faster.

Really? Wont it just rev out lower? Please explain what is "faster" accelerate faster ? more top speed faster? get demerits faster?

Its all a bit academic really , if the bike is on the list you can have it , if its not you cant.

Fuckin aye spot on.

The publics perception of bikers will ensure this legislation is passed without a doubt - but in all honesty what they know?sweet fuck all
