Twist-grip spring tension on ride-by-wire throttle

Is it possible to make the ride-by-wire throttle grip feel more like a mechanical cable-operated throttle?

This is my 12th motorcycle (4th Ducati), but first one with a ride-by-wire, and I honestly don't like the loose feel of it, and wish it had more tension on it like a "real" throttle.

I just picked up the 2013 Hyperstrada last week from Westlake Ducati (used with 5k miles), and have only ridden 400 miles on it (I flew down to Thousand Oaks and rode it home to San Jose). So perhaps, I'll just get used to it?? Feels super strange when I switch from my CBR600RR.

I don't see how it would be any different mechanically than a cable operated throttle. They both use springs for tension, this one just doesn't have a cable, which I don't think really adds much resistance to old school throttles.

It is definitely a race-like, shorter throw throttle, which some have commented on here. Think it's just designed to be snappy, or, dare I say..."Hyper".

My ride-by-wire throttle has been changed and the newest one has a harder spring. Much more easy to handle in city.

@ niiico,

are you sure the new throttle have a spring modification maybe the spring was faulty from the beginning? I never had a problem with the spring tension!

Last year i try the MV Augusta BRUTALE 675 with ride-by-wire throttle. There was a lot of space for improvements compared to the Hyperstrada!

I read other threads where people said that the spring was harder after the throttle change. I tested two 2013 hypermotard and the throttle was very sensitive. Difficult to ride safely in town on bumps in sport mode. With the new one, no problem, the harder spring avoid any unsollicited twist.

There may have been a change on the product line in 2013 and you have the new version. My hyperstrada was bought in may 2013.

@gatdammit I believe the key difference is that on a traditional throttle, it's the springs on the throttle body or carburetor(s) that produce the tension for opening the throttle whereas on a ride-by-wire system, that tension is artificially replicated, or mimicked I should say, by some kind of coil or spring inside the throttle grip unit.

I prefer the analog old school throttle, but the ride-by-wire system includes traction control and 3 riding modes, so it's a trade off.


@niiico Was your throttle changed by the Ducati dealer under warranty, or did you pay to get a new one for some reason?


My bike is a 2013 model (not sure when it was first sold), so maybe it has an older weaker spring??

Using Sport mode, especially in town, makes it much harder to launch without having the clutch grab. I think that's why the magazines whined so much about it. You still get full power above 4K or so in Touring, so why use Sport all the time? Maybe some macho thing?

Touring mode doesn't have the same response above 4k as sport mode. It may have the same power, but the delivery is still softer in touring mode. I use sport mode all the time, and I can tell the difference to touring mode. It makes a big difference with just using the throttle to pass somebody on the interstate.

Good point, Joe. I almost forgot about spring loaded throttle bodies. All my vehicles have TBW.
