I wouldn't worry about the off road performance..

True for me. To me, "off road" means not only off pavement, but off gravel, off dirt road, off two-track.

If I had an Explorer it would only see true off road if I made some sort of navigation error.

According to the VisorDown review, top speed is e-limited to 220kmh (approx. 137mph) for "hard-luggage stability issues".

You probably know this, but you can get some weird handling issues at speed if you load a bike too high and too far back.

I have one of the last very large top cases that Al Jesse made, and I had to beg and plead with him to get it. They were meant to be placed over the passenger portion of an R1100GS or R1150GS but he had too many people mount them too far back and get into some sticky wobbles, so he took them off the market.

Well, there ya go. Triumph have made a luggage system that isn't designed to give at high speed (there is some in-built flex).

But, for everyone gagging for spoked wheels, there will be a numpty doing 137mph flat-out, fully-loaded, crashes, and blames the spokes.

So Triumph, for now, fit the cast wheels only.

The "good news" is said numpty won't survive the crash....so nothing to complain about really.

Then what's this "Trophy" version I keep hearing about.....spokes, crash bars, etc......

I just need to replace the battery in the Capo, and make sure everything else is fine on the bike - the Capo that is. The Tiger is totally in perfect running order, eh.

I'll shoot ya a PM in a few moments.

Oh, besides that .......

Trophy is a tourer - big screen, full fairing road bike. Won't be with spokes.

Reduce output? Surely that's not the gear losses. Must be the ratio.

nope, a shaft drive is only about 80% efficient - think chain is 90%

I hear that. My Strom has suffered a fair amount of "User Error" related scuffs and bangs.

Yep, parasitic. 110 to 115 to the rear wheel would be on the high end of what to expect.

Sad, in a way, that the desire/need to serve the shaft lovers has essentially neutered any gains they made with the new 1215cc motor.

Here's hoping they use that powerplant in a chain-driven platform as well, where it can really shine.

Power losses in a gear assembly are always related to mechanical losses. Power in different transmition ratios is always constant, what changes is the momentum aplied on the secoundary cog/wheel/whatever.

Imagine that you are pedaling on a bicycle, transmitting 1KW to the cranks. If you are on the granny gear at front and the 32t cog rear you are apling 1KW (ignoring mechanical losses) to the rear wheel. as well as a reasonably big momentum. If you change to the big chainring at front and the 11t cog rear you'll be apling the same 1KW to the rear wheel, only with a much smaller torsional momentum.

They must be using some crappy gears. One extra right angle to get out of the transmission and then a spiral bevel at the rear.
