Gearing

Hello,

New Forum member here from Australia (will post in new member forum when I purchase)

I have many years riding experience and about to purchase a 790 Duke when I sell my current bike, 2008 Guzzi Breva 1200

I have one question, what RPM does the 790 Duke sit on at 100 kmh (62 mph) ?

Cheers from Oz

I'm assuming you are asking about sixth gear. If so, you won't want to ride at that speed in sixth. The engine isn't comfortable under load below about 4500 rpm.

4th gear - about 5500
5th gear - about 5000
6th gear - about 4500

Agreed with GOTJ. I usually stick around in 4th gear at that speed for just rolling down the road. Sometimes I will hit 5th if it's a real steady roll and I am trying to conserve some bit of gas, but I like 4th for that speed. The power is there at a moment. At 4500 RPM. it takes a lot of throttle and a good amount of time to hit that power band. I usually don't even use 6th unless I am over 70 MPH on the highway and cruising.....which all equates to the RPM and where I like to ride.

If I'm sticking to the open road speed limit on straight roads in NZ (100 or 110 km/hr depending on the road), I normally stay in 5th gear for the reasons other posters have mentioned. It's actually less sensitive in Rain Mode if you're just out for a cruise rather than a fang. Welcome to another "mature" rider - I started riding in 1964

I ride because my wife says it keeps me young and is better than if I get a girlfriend...

When I checked this I am sure that the RPM at 100kph (62mph) was around 4200. To me that is much the same gearing as my VFR 800. But the VFR would rev and rev, so at 10,000rpm in 6th the speed would be 238kph, at 11000 and peak power the bike was near 260kph- and it would do this speed! The Duke 790 seems a lot more relaxed having only half the number of bangs per minute. I find the gearing quite tall, having to notch 1st for all hairpin type bends and even some roundabouts. I am trying to discipline myself to keep to 2nd gear for roundabouts and feather the clutch MX style if needed. No criticism meant. I prefer tall gearing so am very happy with this bike.

Yea, I have been checking this every time I ride now just to see. I was a bit off, the RPMs are actually a bit lower than I originally post (which was from rough memory). I'd say they are about 350 RPMs lower.
