Classic simultaneous torque hit wheelspin/wheelie

Of course you realize that this movie was directed by Kiwi bike nut Roger Donaldson, but it aint no C.G.I. bullshit, nah - that is real old school two stroke torque boys.
 
Pashaw, Its merely a very low 1st gear chain saw tranny ratio torquer, not ballsy 4 stroke twin hit off idle. Used rear brake to slide a squeal the first time. He leaned tire before nailing to get lower traction too. Must have pretty hi air pressure in rear to spin a hi pitch squeal instead of tire howl leap or just pop a wheelie like they did in real life against a real hot rod P!! If they'd put a bit of castor oil in the mix it'd not smell like an outboard motor either. Still a nice skill to handle the tall wiggle thing but fits the movie part of an obnoxious character.
 
& remarking on chainsaws, even 4T devotees Honda haven`t been able to build/sell a cost effective 4T chainsaw, which,since 4Ts generally are lazy without forced induction, so must be heavy, complex & expensive,needing a dry sump/scavenge for all angle use, hey wait, maybe a Norton mill could cut it .L.O.L.
 
I just spent the weekend riding fireroads on the 490 Maico.
You can call it torque or you can call it horsepower, all I know is there are great gobs of sheer power available at any time.
Ive never ridden any four stroke bike that can produce the brute acceleration of the big Maico. The 450 ktm is nice, but just doesnt do it.
And unlike the Japanese 2 stroke mxers, the Maico has a broad spread of power and a duplex chrome moly frame that is the mx equivalent of a featherbed.

Dirt bike Magazine recently declared the 81 490 to be the best open class mxer of all time. The 82 has even more midrange grunt than the 81.

There is nothing that compares to the thrill of cracking the throttle on a big bore hyper two stroke!

The 2 smoke race tach shows the power band don't kick in till over 5-6000 as it peddles its way around, thrilling as can be of course. WOT racing ain't living with a 2 smoker in real life traffic annoyance. I like the hits of big bad 4 stroke myself but for outboards and chain saws. Put a dash of bean oil in Norton tank for some nicer smoke flavor.
 
You need to ride a 490 Maico some day.
Power is instant and everywhere. There is no waiting around for 5 or 6 k, the hit occurs the second you touch the throttle, regardless of RPM. The biggest problem is reminding oneself to repsect the power, plenty of people have come off those Maicos with a broken back.

He`s correct you know, & I have a KTM 380 Enduro as a dual -purpose single, not a full-size MXer.
But I do commute on an RZ 350 Yam, which, with its asymmetric reed valve/variable exhaust porting rotary valve set up gives a similar out-right performance to a Commando[not in a top gear roll on below 6000rpm,obviously- but ~60hp 125mph], even doing 50+ mpg if you stay under 5500rpm [~75mph].
Of course it does not compare with a big cube 2-stroke which effortlessly rips through its tall gearing, so eagerly, yet will also purr around at low engine speeds on a whiff of throttle.
I really suggest anyone who doubts this gives it a try, I`d be happy to lend any of mine to a Norton guy in exchange...
 
Ok Glen, no denying some 2 strokes are right now torquers, just not the few I've tried to ride. Would be educational to compare the lower gear rations with similar power 2 vs 4 stroke. A lot depends on how the 2 stroke is ported and piped, but I'm not educated in that area. Once in a while I almost fall backwards with idling chainsawing on slopes so swing bar down into bark then nail 6 hp saw trigger and usually growls right up to pull me back towards the log w/o actually cutting through the bark by reving very much. That does impresses me to have to agree I'm generalized to far. My P!! drag bike didn't lean so used it off idle instant tire spin to swivel it to face new directions w/o accelerating much. I had to on purpose be very careful not to nail it leaned a little like the NYC 2 smoke or would slide right out. Same with passing cars, nil throttle till in next land and lined up or slide out crossed up like flat tracker, not good with oncoming in traffic.

Here's a drag bike that's an extreme example.

Here's a 125 stunter showing some right now response wiping around leaned.

I'll take you up on that J.A.W!
 
From Factory Kawasaki data showing the graph of H2 'running performance curves' giving driving force through gears/revs/roadspeed , & a comment in a technical book in which it is cited, states -
"The 1st gear curve shows a driving force of 550 pounds at 40mph. With a light-weight rider, bike & rider would weigh about 550lbs. If there were traction, he could ride this superbike straight up at 40mph!"
 
From a roadtest in Sept `72 Motorcycle;
"If you do decide to use this muscle you`d better be prepared to handle a 1st gear wheelstand up to 40mph.
The H2 will smoke the devil out of the rear tyre in low, & for the brave kids, its a lot of giggles to ride."
 
& a British view -from 'Superbikes of the `70s'
"The Mach IV [H2] is a machine of strong character & very considerable charm.
The American reputation of unbridled, brute power gives a rather one-sided view.
Certainly the power is there should you want to use it. But the Kawasaki also has a very amiable side to its nature & is equally content to amble along on minimal throttle opening in a high gear."

I know its a jap but my last dirtbike was a 84 YZ490. I was all over the place on that thing. Super powerful. Onlyu problem is the suspension is really lame compared to nowadays bikes. I should not have gotton rid of that beast. I still drool over big old 2stroke dirtbikes on craigslist. The maico would be a treat for sure!
