I've checked mine and found it to be accurate at 100km/hr according to the speed thingy on the Appleby straight out of richmond, maybe it cant handle the combination of bumps on gravel and high speed? (might have a look on thurs night

).

How is your clutch??

Surely Gonzo is not that much heavier than a 640a.

About 190kgs ish with half a tank.

Shit yes, 640A is <165kg with 10L fuel on board. (and mine's 2kg or so lighter without the 2nd front disc & calliper etc)

So in comparison, picking up Gonzo is like picking up the 640A while you are also carrying a 25kg bag of cement.

Yea but on a klr the weight is held much higher to compensate.

Hi, My name is Nordie and I'm a parallel parker.

No wait...

I've seen 185 on the speedo and it was still climbing

You've just reminded me to double check the speed rating of the tires I have on Griffon. Think they are only rated to 160 so must behave or I might bite the dirt big time. Anybody ever poped a tyre from exceeding it's speed rating?

Cheers R

No, but the only carcass failure (small splits inside and out) I've had was the BF Goodrich Crossengo that is only M/130 rated. It only went on the 640A after doing a 6 hour cross country and various other rides, so it wasn't fresh.

!00 or 200 doesn't bother me

(on a closed road of course)

Or I could give you the G.P.S. to check it, probly a better idea, who knows how accurate the Trumpy's speedo is

that is so damn depressing when you put it like that

might sound better if it was a 25kg bag of feathers......

They used to be known to be much more accurate than a typical bike (like 1-2% out rather than 5-10%) but later bikes have the higher discrepancy. Would be interesting to see what the Trophy's is like these days. I know the speedo and tacho exactly matched any gearing chart I calculated, so at least there is a consistent error there!

That's another bike I've never topped out. I've seen 235km/h before buttoning off on the standard 98ps/72kW bike, it was only just creeping up at that speed but seemed okayish up to about 230. Goodness knows what the improved 149ps/110kW version will do. I had it short geared so 6th only did 225 not 240, but got there a bit quicker; those new sprockets are geared to 250.

It certainly gets up and goes still, 180 between the one lane bridges on edwards rd was easy, before mrs Jatz started to hit me

not that I make a habit of that sort of thing

Right, here's another take on the gearbox ratios. The previous charts included the primary ratio, which doesn't alter the gaps between the gears - but does affect the overall ratio.

The first chart shows the gearbox ratios only. The second shows them normalised to first gear. The dashed line is Fran's suggested mods.

Interesting, eh? Much closer than previously thought. Dunno what to make of that!!
