I've done over 700 miles now on my Classic and frankly have no issues with the throttle response. Yes, it is quick but no more so than my Multi in Sports mode. My bike does have the Termi exhaust though, with it's upmap, which might improve it's small throttle opening characteristics.
What I do have an issue with is gearing which I think is too low, particularly 1st gear. On approaching a roundabout (circle) or give way junction, on most bikes I'm used to snicking it into 1st, feathering the clutch if necessary then opening the throttle to ride on if it's clear. Initially, until I got used to it, I found that on the Scrambler 1st is too low and the rate of acceleration can be faster then intended. Now the 796 Monster uses a 15/39 sprocket ratio while the Scrambler has 15/46 with the same internal ratios so it's not surprising that it's quick off the mark in the lower gears and runs out of revs very quickly. I've partially improved this by fitting a 44t rear sprocket which is the smallest I could fit without shortening the chain but when it comes to chain replacement time I might reduce this further to 42t. Of course my riding is entirely on the road, if I intended to use it off the tarmac I might prefer to keep the lower ratios.

Like you I fitted a 44t rear sprocket, it suits it perfectly for my riding and local roads ;-)

Hi Hui

Just to clarify, it occurs with a warm engine from tick over revolutions to 2500 rpm in first and second gear. Is it smooth above 3500 revs when speeding up in all gears, say in slow moving traffic streams.

Does it happen on bumpy roads or all the time?

Is it all the time or above 18 degrees celsius air temperature?

Is it better or worse with a full or low level of fuel in tank?

When starting engine do you just press the starter button and let it get started on its own not having any contact with throttle grip. Do you hold throttle when starting and twist to catch the revs.

I have a few ideas but trying to eliminate as many as possible to try and pin it down. Thanks for any feedback, just trying to help.

I don't have a problem with a sharp throttle but I can feel what others are saying.
Being fuel injected plus Catalyst, that means the throttle should never be opened when cranking the engine to start. This will result in excess fuel and poison the cat.
The sharp throttle is there at all temps. and just off the tick-over stop whether on off the throttle up the rev rage or not.
Fuel tank level should have no affect as the fuel pressure is regulated.
Bumpy roads will exaggerate the problem by causing involuntary throttle movement due to zero tolerance with the throttle body/throttle twist grip response.

Well I've done over 1600 miles on mine now, I have tried every which way to improve the throttle in certain situations and IMO it can't be done - on my bike anyway. I don't ride with a 'death grip', if I had any more relaxed hold I wouldn't be holding it! Over bumpy/uneven roads especially low gears mine CANNOT go without jerking, clutch control can improve things but not 100%. My throttle is also quite loose on the bar (as mugwump said). I noticed that if I slightly raised myself from the saddle things improved vastly - indicating that the suspension could be a big culprit transmitting directly to the throttle hand. SO I have just had a Nitron shock fitted - and on first impressions this has most definitely made things better. I wasn't able to go far but even down my extremely uneven farm lane there is a big difference. The throttle is still sensitive but isn't being jarred by the stiff suspension. I'll update when I've had a chance to do more miles, when it stops raining!

But do agree, it's an issue for too many people including professional road testers, that either the throttle or the suspension should be addressed by Ducati.

I know exactly what you mean, not sure if you've checked tyre pressures but I've lowered mine to 32psi rear as when following my wife riding my Scrambler there is NO flex at the rear tyre whatsoever. My feeling is the pressure could easily go down to 29 or so which is the same as my Supermoto (factory) without any adverse affects which will improve comfort and allow a proper contact patch to form.

This looks cool. Could you lead me to a sprocket reference which fits the Scrambler ?

 

[nuttynick]

If I wasn't on my phone I'd post a link, but do a search on here for sprocket tips. The one I fitted wss an 899 Panigale 520 conversion one.

 

[Piero]

Thx nuttynick I have found one BIHR - Couronne Afam 44 Dents Type 50613 Pas 520 Acier Ducati 899 Panigale

 

[ELVISTO]

I think Nutty used this one from Renthal 435-520-44P-HA Ducati /Ultralite,

 

[Geeza]

I did some adjusting to the throttle cable today, ie taken out the lash so less play on the grip now! Seems a bit better! But do you think that fatter grips might help? As I do have rather big paws!

 

[mugwump]

Never been off roading not likely to either tbh bit of gravel or the like, not buying the scrambler to scramble, I like the style and lightness of it. Anyway, the more I delve into the sprocket set up the more it seems to be the problem. For off roading I'm assuming that a 46T would be fine plenty of throttle needed up hills etc ( who knows!) But the 44 or even 43T would be far better for road use maybe a remap is needed as well.
But would appreciate input from those who do a bit of off roading on the subject, mate told me that our local dealer are going to have a play with rear sprocket, the guys race so if they are thinking sprocket!
If £30 solves it!!!

I did 100 miles on the new shock today - I was trying to find all the potholes and bumps I could. It has improved the snatchy throttle amazingly, so much so that I can live with it now

 

[ELVISTO]

There you go,

Good to hear; makes the shock more than worth the money.

Call me old fashioned! But changing the rear shock won't improve the throttle response! Just stop the riders hand jiggling around so much, which goes back to the your holding it to hard! so doesn't solve the problem it just makes it slightly more manageable.
unless these days fuel injection is conected to the suspension?
It's the mapping and/ or gearing but mostly the rear sprocket if other dukes have 15/39
and were supposed to deal with 15/46 fps!

No it doesn't solve it, but does make it a LOT more manageable, unless I'm totally imagining it? I haven't been holding it too hard, and IMO the suspension if hard will directly affect the throttle hand if the throttle is super sensitive? Yes I am sure that other means may address it better but for me it has improved to the point it's not a huge issue now.

Riding 2-up, the throttle is fine. The lightness of the bike, especially for smaller riders, is the big factor in the throttle being "too responsive". No way that I want to diminish mine.

As I said back in the start of this thread, it's the riding position & the harsh suspension that needs to be addressed.

Yes...the "hand jiggling too much" IS the problem.

 

[Shamone]

I'm very happy with the Throttle Tamer I fitted. It only affects the first few millimetres of travel and after that it's normal.

I take your points but not having had suspension for many a year ( hardtailed ) seemed odd to me! No offence meant just asking!
I'm used to being able to adjust my throttles tension roll off and find the complicated route the throttle cable wire takes odd as well.
And people say Harley riders like to make life as difficult as they can. So far riding the scrambler seems very complicated for a modern bike.
time will tell whenever in the hell mine turns up lol
but I do think a rear sprocket change is the way me, myself and I will go !
And maybe I need to hold off a bit I'm used to a building forum where we say it like it is and critism of the wierd and wonderful oddness of approach to building a bike is expected and welcomed along with Damn good arguments and verbal punch ups .
As said no offence meant!

 

[Ogre]

No offence taken, by me, at least.

I am going on a week long tour through the Appalacians. Since we will be staying at a different place each night, my bike will be loaded the whole time. I think that I will appreciate all the snappiness that I can get.

 

[littleowl]

No offence taken either, just defending my corner :stfu: . We are all going to find it a little different to ride as we are all different shapes and sizes, as I am small, relatively light and have barely any effect on the spring, I have found the suspension to be a big issue in keeping my throttle hand steady on bumpy surfaces UNLESS I rise out of the seat a bit - so that to me indicates it's a factor, as has been proven by fitting the Nitron. Not everyone will want to change the spring, some will be fine with the throttle, some will find other ways of coping.

Yes I have been on many a forum where arguments and punch ups are a frequent occurrence - but they very often get out of hand! ain10: :violent1:

It will be interesting to see how you find the bike once you actually have it!

 

[Ogre]

I suggest a little experiment...

I know a lot of scramblers will be solo bikes and never see a pillion rider but find a willing passenger of 150 pounds (or more) and go for a little spin.
