Not necessarily; if the engine is not poweful/torquey enough to pull a high enough first gear to get to 60mph then it will be quicker to shift gears than try to use too high a gear ratio.To get the lowest 0-60 times its best if you don't have to shift. I think that is where Wheellywillz is coming from.
Yes; a 300hp, supercharged 1000 can take a higher first gear than a 100hp 600.True enough. If you watch this vid, you will hear quite a bit of clutch slipping coming off the line but you can also hear his first shift at about 140 kph. This H2 can go for 0-60 MPH in 2.98 seconds.
A standard H2 from 72 would not hit 60mph in first gear mate. Not even close. 2nd gear yes.As you pointed out it all depends on HP/Torque curves. The 1972 H2 triple had only 74 HP and could hit 60 MPH in first gear. But I agree with your point that the ability to do that is not necessarily that fastest way to get to 60. Shifting takes time and slows you down, but so does slipping the clutch if the gearing is too tall.
Back in 1972 though, I don't think there was anything in our town that could touch the 0-60 time of the H2 left in first gear. It was a beast.
All been there mate. I think the thing that sticks in my mind about those early triples was the wicked power band that made riding them so addictive compared to anything else on the road at the time. Small, poor quality tyres, dodgy suspension, frames that flexed and no speed camera's. Riding heaven. Those were the days. (Wildly optimistic speedometers were also good for pub bragging. Ha! Ha!)Hmmmm, digging into this now I see you are correct MichaelZZR.
My bad. Memory from so many years ago is faulty or my buddy who owned an H2 triple was just pulling my leg. I was so sure of that fact, I don't know where it came from.
Based on performance curves it looks like first gear tops out at about 46 MPH.
