How come?

How come

Italian bikes and Japanese bikes have very different gearing?

Italian is typically very tall - 6th gear - click that bad boy in over 120 ....

Japanese at 120 - looking for gear 7 ....


Been this way for decades.

Why?

You may just have to try a big Japanese bike for this Busa rider doesn't share your views...

Was thinking that. VTRs and SVs are geared way too high.

When i had my SV and changed chain/sprockets i went 2 up on the rear - much better altho speedo was about 10ish kph to high.

Given torque X angular speed = work done.
or ftlbs*rpm=HP

How a bike feels under throttle and how much horse power it produces at full revs are often misunderstood. HD's produce adequate torque at low motor speed so feel powerfull at slow speed. R6's produce great HP at high motor speed so go fast.

Not true - my big Bandit comes on song in top gear at 120 klicks ... It will handle 100 klicks in top, but if I want to pass anything I drop it down two gears and open the throttle ... at 100 klicks in top it's a bit sluggish until it gets up in the rev range ... and I've been to 200 klicks in fourth gear - not even on the red line ... I don't need a seventh gear ...

Me neither ...

Too funny.. 600/4 TQ is piss-weak.. they have to rev their bloody tits off to make it do some "useful" bloody work..

Umm err .. my 650 bandit (not a sports bike) hits peak horses at 9500 revs .. (sure, that's up there) and in top gear 9000revs is 180 klicks .. I rarely use peak HP in top .. in the lower gears it 's a missile .. I would not describe it as 'piss weak" ... sports IL4s are just awesome ...

I purposely chose an R6. I almost said an RZ350 has about the same.

Hardly.. RZ 350 is long finished before 10,000rpm & R6 aint started doing anything much - at that point..

Ride a GSX-R 600 & 750 back-to-back, the seemingly piddling 150cc makes a big difference ( improvement) - to riding feel..

F5 knows all about sports bikes, RZ's ZXR's and things that go vroom.

So what.. why.. don't you?

Now you've bloody done it Dave! People struggle to get their heads around the accurate description of 'horse power', and you want to go muddling up what torque is. Torque is how much force is being exerted, rotationally or in a straight line makes no difference. It can't be measured in any way other than direct pull or push. So although in this application something is being turned, that doesn't mean rotation is integral to the force definition.

In a tug of war, the winner is decided by who applies the most force on the rope. Torque is a unit of measurement one could use to quantify it.

This can all be cleared up in two 'formulae' Drew

1} Horse power, how fast you hit the wall, Torque, how far you drag the wall with you.

2) Hardly Rideitson's, the world's most efficient mechanicldevice for turning liquid hydrocarbon into noise, without the byproduct of horsepower.

Measured somewhere useful like the rear wheel, Harleys have comparatively poor torque. An R6 hammers one. Or were you meaning something else?

Except the Hardly produces that torque 'low down' rat HD Vs 1000cc Blade

and there are many V twins that produce more torque low down than a sprotbike produces at 'full' song.
My MT produces over 160nm's, {150+ standard} never less than 120nm's low down, that was more than a 'busa' made untill they retuned the motor, in recent times.

Yeah .. but that should never have happened - the Blade rider is shit useless at launching his bike ... I laughed my arse off - three times in a row Hildo beats him ...

Ever drag raced against a Harley? Clearly not.

I'm pretty handy off the line. Could get my 749r to keep pace with decent bikes racing in F2. Mother's day races, front row surrounded by wooly butt fuckin Harley hillbillies in jeans and steelcap boots, what place do you reckon I was coming into turn one?

They leave the line insanely fast, fuck all can keep up till ya hit 80 odd k's.

Just need a decent clutch, & know how to launch..

& on an RZ 350 its too easy, dial 6G, feed the clutch, WFO - punch it out.. keep the front wheel hovering 'bout 200mm through 1st.. hole-shot.. MX-stuff..

Ok the quicker machines ( only V-rods, near-stock H-D-wise) will go past after 2nd.. but you still whip 'em off the line..

Bollucks. Maybe a sporty, but I'll wager Rossi couldn't get an RZ350 to launch better than a halfway decent rider on a big block.

[J.A.W.]

What showroom stock 'big-block' H-D does mid 12 sec 1/4 miles?

[J.A.W.]

I love doin' it.. its a hilarious party trick.. anyone who has gunned a decent 2T MX-er can do it too..

The look on those H-D guys faces is priceless.. you become invisible.. so - "it never happened" L.O.L...

Here is an RZ 350 test.. 12.66 @ 171 km/h on the way to 198 k/mh top end.. www.rd350lc.net/Magazine/CC_7_83_8full.jpg
