Initial Ride Feedback

Playing with gear and final drive ratios (much more difficult than I thought to figure out), I am coming to the following conclusion:

- The primary and final ratios are overall a little taller.
- Triumph followed the standard practice of closer spacing between gear ratios with a taller 1st gear, 60mph can be hit in 1st using the stock redline (explains the insane 0-60 claim).
- It seems 6th, is actually, slightly taller than our 5th, 2900 @ 80mph vs 3100 @ 80mph.
- 138mph governor can be reached in 4th gear :(
 
Third gear from the same video. It isn't sharp, but it must be mph, right?

That road sign is in KM - so my guess kmh.
 
My guy in Triumph told me 80mph is still 3000rpm, in 6th on the new Rockets...

~80kph @ 2000rpm

I think the speedo shows mph in this video, so 53 mph in 6th at ~2000 rpm

Aaaaaaand there you go.. thanks kluven for proving me right :D

53mph @2000rpm = 79.5mph @ 3000rpm.

53mph is also close to 80kph which might explain the 80@2000rpm statement.




I'm going to be an argumentative so-and-so here :p

Conflicting info then. The screenshot in post 11 shows 130kph/80mph

That was drivetribe "at a guess"...

I guess in the long run, an enterprising individual could get in there and make some changes to the gear ratios. At least the spot for 6th is there

Would effectively be the same as changing our current 5th's ratios, since ours does 80mph @ 3000rpm in 5th and the new bikes do 80mph @ 3000rpm in 6th... and nobody did this mod with the old bikes because.... (reasons)

Looks like 4th is essentially exactly the same ratio as the 04-18 bike, however, need two data-points per gear to fully work out the gearing and confirm final drive ratio.

Afaik you need either the Triumph manual/spec sheet, the paired gears' teeth numbers, or the input & output shaft speeds per gear (with accurate tacho & speedo readings), to determine gear ratios.
We don't have any of this info...

If you assume the speedo and tacho info from the pics/vids is accurate (just to get an approximate gear ratio), you will also need to know the crank vs the primary gear on the clutch ratio to determine input shaft speed,,,,,
need to know the circumference of the rear wheel (easy figure out) AND the final drive ratio, AND the torsional damper (if it has one) ratio, to determine output shaft speed....

There are a lot of unknowns there... unless there is another way of calculating gear ratios?

True but the imported bikes have English registrations (high certainty = mph)

Will it beat the old rocket with NA mods when the traffic light goes green ? I love new bikes but can never afford/justify the price tag. I would need to wait for 3rd gen and then get this one as used :)
But really hope the less financially challenged show up at my local meet with one of these.

You are correct Arto. You need driver and driven information , only other was are teeth are in ratio, and pitch diameters are also in ratio. So I'm still waiting for a manual to come out :) still like the looks of the bike. Not sure if I'll get one or not. But if so I'll let them work the bugs out first this time.

Correct on all accounts. You can work out something close without any of that info by working backwards. I figured you were correct to begin with, which is why when they said 2000 ish at 80MPH seemed suspect right away, but 80KPH it made sense.

Yes it ASSumes the speedo and tach are correct, which, they're not because it's numerical and has a delay, and is probably reading a little high like 99% of motorcycles. Due to known speedo innacuracy I didn't bother trying to find the exact ratios, any backwards math is bound to be wrong because of the speedo delay, but you can get an idea of the gearing still.

Take two speed vs RPM values for each gear. Then work backwards until you find the right ratios (i cheat and use gearing Commander to do the math). You don't need to know all those different ratios, you only need to figure out 7 ratios total, one per gear and then the 7th is the total output ratio that each is modified by (a total value accounting for primary, final, and damper). It's the same way it's done for the old rocket on gearing Commander.

Wheel OD is the same 240/50R16, no change.

I can say for sure, it's a taller first with closer ratios between each gear after that,

For others:
It's also got reduced power in 1st and 2nd gear, like the early bikes, but it'll still smoke the old bike off the line.
