"Twitchy" throttle - rode two SM-Ts back to back

Squeaky back brake? Hard to control at 30mph/40kph?

I traded 2 bikes in to get the SMT...a K7 GSXR1000 and a MK1 Tuono.....both were great at their own specialities but wanted to do it all the time...at least with the SMT I can tour and holigan...i notice some have said they don't wheelie well....ooops i must be doing something wrong...mine loves to lift in 3rd exiting roundabouts..no clutch work needed...just gun it....should be a laugh once i play with the gearing.

Running in I suspect is important on these bikes.


I have ridden mine quite hard from the off , but whilst using most of the revs, I didnt overstrain the engine.
Acceleration then lifting off is supposed to generate vacuum in the cylinders, and has worked for me in the past.

I also have been running it at quite low rpm with no load on the throttle, or very very little, in town.

She now runs smoothly at as little as 2,000rpm.

I think the trick is to use the top and the bottom of the rev range judiciously .


Yes, its still quite enthusiastic, but even with only a few miles my bike also is starting to feel smoother.

2nd that, running in engines..........
I have always run bike engines in using most of the rev range but try not to put the engine under strain at lower/higher revs and always keep an eye on Oil and other fluid levels

Seems to me the throttle is OK and you get used to it. I find it less snatchy than my old bike - a BMW F800R - and a bit smoother on the engine overall.

What a great bike the SMT is!

If by "twitchy" you are talking about the immediate hit of power from the slightest crack of the throttle as a negative - then I cannot join in.

The immediate response of the throttle is one of the things that I loved most about the SMT and reminds me of my old 2-smoke dirt bike days. I love it, love it, love it!!!!

Stock, the bike was a dog. Surged at constant rpm, didn't seem to want to rev and restriction in 2nd/3rd took a bit of joy away. 1st service done, SAS/O2 gone and Akra pipes on and the bike is transformed. Whether in town or out and about, I love this bike more and more with every ride.

OK, now I have to get my nerve up and try a bit of wheel lofting and a signing up for a proper track session.

After the first service , my bike no longer surges and the throttle is smooth as silk.

I think you need to run these bikes in quite hard to get a good result, and have a dealer who sorts the mapping at first service.

Get Phil to set your suspension up for your weight and taste.

A few very subtle changes to mine have transformed the handling.

Yeah, I was reading the suspension set-up posts on here and I couldn't help thinking how it was so easy for us to get it set up right :D :D :D

Get rid of the O2 sensor and remove your secondary butterfly... and bob's your uncle!

I`d still argue that there is no need to spend a fortune and lots of time fixing a "problem" that doesnt exist.


I`m back on the DRZ 400 for the winter as of this week and whilst I dont need to feather the throttle I miss the sharp edge [and power!] of the KTM.


Much easier to handle mind you riding home from work in heavy falling snow last night!

The snatchy throttle is the only thing I can honestly find wrong with my SMT. I've got Akrapovic slips-ons and the KTM factory mapping for those mufflers. As long as I am rowing through the gears on twisty asphalt everything os magic. Tip-toeing on a tight, bumpy, gravel strewn road is awful. If I let I friend sample my bike I always warn them to be careful at low revs, it can be like a bucking bronco. The throttle cam with the longer ratio may help a bit, but it does not really solve the issue. At some point I will address this problem as I adore this MC!!!. I know MCN were able to sort out their bike and I believe in required removal of the O2 sensors as well as a custom map. See, "Returned to Perfection";

First ride a high powered enduro bike then jump straight in the SMT. It really is a question of getting used to it - learn to be gentle with the throttle and use the clutch more like and enduro rider would.

Yes, big twins tend to feel lumpy on the bottom, but the choppy on/off of the SMT at low revs is a definetly a flaw, probably the result of emmssion standards. It can be fixed, making the SMT smoother and faster.

Agree totally with Jonty,I can't see any problem to fix! If your used to Multi cylinder
Bikes ALL V-twins will feel lumpy and a little snatchy.
I spent a lot of money on my first Tuono trying to make the bike smoother,can,airbox conversion,front sprocket etc. and when I got my 2nd one I left it as it was.
IMHO these are characteristics rather than problems!
FFS just ride it!!!

Akros and map, all SAS stuff gone but 2nd butterflies are still in place and the surging is gone.

By snatchy, do mean the surging that the bikes do when new?

Throttle is twitchy and by that I mean, a slight twist of the wrist and the bike springs to life. Which I love!!!! My hat is off to KTM to make be forget I am riding a twin and fooling me into believing I am riding a dirt bike.

KTM make a set of cams that can be fitted to the twist grip. I have fitted the softest one and it works very well.

Hi Guys,

KTM supply a set of throttle cams which I find help greatly with the inherent problem of an eager throttle response as you first start to open it.
The throttle is now superb.

Cheers
