When the tach on my Bassa fails, I'm just going to switch to a single instrument panel. - Rich 

Rich, I'm ahead of you. On my Bassa, the odometer went first, then my tach, then the trip meter followed by the speedometer.

And while I wait for the shekels to fall from heaven to finance Speedhut hardware, I'm keeping an eye out for a Jackal instrument mount.
That's the combustion chamber of the turbo shaft. It is supposed to be on fire. You just don't usually see it but the case and fairing fell off.

Don't need it, but I want it.  Gives me a good idea of where an engine begins developing power, and the useful rpm range (without flogging the crap out of a bike to hit the rev limiter.)  Example - going from riding twins for the past 25 years, I find that the recently-acquired Honda CB1100 develops great torque and hp at relatively low rpm.  And for some reason, when I think I'm over-revving the IL4 engine, I look at the tach to find I've got a long way to go, rpm wise.  Unlike many in-line Japanese fours, this engine has been designed and tuned to make max power down low.   The redline is at 8500rpm.  Maybe my ears are playing tricks since most of my auditory experience on revving engines has been on either flat or 90 degree v twins.  I like having a tach.

On my Stelvio it was all too easy to cruise at 70 mph in 4th because the engine was so willing and smooth.  The tach told me that it was time to shift up...a couple times.  I really appreciate having a tach.  Too bad the V7 III Stone lacks one.

Unless you get the anniversario (spelling?), then it comes standard

But man my OCD will not allow that shiny chrome to be in contact even the air lol....

I felt the same as you old timers when they started putting the gear indicator on bikes.  Now I like it because many times I am cruising in 5th when I could be cruising in 6th for better fuel economy.  :)

On my Guzzi, I watch the tacho closely. This is because shortly after buying it I had a piston to valve moment that was probably (at least in part) caused by too many RPM and I'm now paranoid about not repeating that.


On both my Ducatis I don't really pay much attention as I can feel the sweet spot easily, they both have rev limiters and, being Desmo, over-revving won't cause a piston to valve meeting anyway.


The 916 pulls strongly all the way to the limiter (makes full power just a couple of hundred RPM short) so I am used to being able to safely wring it's neck - which maybe the attitude that got me in trouble with the LM2? so whilst the Guzzi pulls well to 7k (maybe beyond?) but seeing as there is no limiter (and my past history) I don't want to risk it so generally don't venture beyond 6k so am glad there is a tacho.


The Monster, on the other hand runs out of puff before the limiter and responds better to short shifting so has the least need of a tacho of them all - Other than on the dyno I don't think I've ever hit the limiter.
