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?


Side note. WTF is the point of a six speed Harley? Big fat torque beasts - fuckers only need 4 gears.

Now what are you riding? Top gear on mine is fine at 100 unlike the superduke I tried.
What is a bit high is 1st gear though but not unlike some litre Japanese bikes I guess.
Mines got anti stall assist which lets you edge forward with no throttle applied. Handy in traffic.

What you need do is buy a MV Agusta and keep your Hornet for around town.

Like what? How many rpm at 120Km/h? Twin, triple or four? How many cc? Lotsa variables eh, mite..

H-D's have short rpm range, so they need all those ratios or else they run out of 'em..

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

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

Sounds like a clutch lever to me. How does the MV system work?

Was going to say the same. Even on trucks the engine computer knows your taking off and wont let it stall unless your a rough goober.

you mean the v twin ones aye?

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

I just call that torque. I tested it, the CB919 can get into 6th with no throttle (just easy on the clutch, let it out, change gear, rinse and repeat)... you're doing about 30-40kph.

As for bike differences you've got to think geographically. Europeans design bikes in their thinking. There are few areas that gas isn't every 50-100km. Towns are close together for historic reasons, as it was horse and cart. Therefore, tanks don't need to be large, plus that extra fuel affects handling. Due to traffic, heat and very tight roads in some regions, it's rare to see anyone using large bikes for practical daily commuting. Scooters take up less space parking, and so bikes are weekend playthings.

Speed limits in Europe aren't as heavily enforced every where like here (some places they are) but therefore speeds can be comfortably higher, and having top gear for 120kph is also more fuel efficient. My KTM 990 was 130+ for 6th until I re-geared and re-tuned, then it was 120+.

Japs don't have a sense of humour. It's practical. Character is simply bad engineering and they can do better than that.

Why does this worry you?

It controls throttle slightly for you. Even on a hill start you can let clutch out slowly without touching throttle and it will self propel about the same speed as you would edge forward in traffic. Perhaps 1/3 walking pace.

Fuel range on mine seems about 190km before fuel light which has 6 litres left so 16 litres used approx.

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

Torque is the ability to rotate something. Gearing lends incredible mechanical advantage. But it is a widely misused term.

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.
