So I have 360 miles on my new 796  and I have been questioning the way the bike is supposed feel during a down shifts. My bike feel's like it thud's into any gear will down shifting .

The technique i have been applying has been to pull in clutch roll of throttle down shift smoothly let clutch out will applying smooth throttle input the transmission  in a harsh way thuds in.

I have never owned a ducati before or any other bikes. I really am hoping im just being paranoid. Up shifting doesnt feel the same way. I guess im just used to my WRX I can shift through the gear perfectly. Can someone help me out with this question

Just make sure you are pulling the clutch lever all the way in when you are briskly depressing the shift lever. Your timing may be off and you don't realize it? Naturally open (not close!) the throttle a hair as you do the above. You are trying to match the engine speed with the lower gear. It definitely shouldn't "clunk" into gear when the engine is warm. Cold of course it will on that first shift into gear.

WRX car?!  Cool Those things have no torque.  Grin Try doing that in a V8 or boxer 6 without matching revs and see what happens.  Wink (You'll think you popped a parachute!)

What Curmudgeon said.  I use a sharp blip of throttle on most downshifts, dropping into first is different depending on speed and engine load.  Sometimes a slower more gentle roll on of throttle during the shift makes that one seamless too.

You need to learn to blip the throttle too...  Cool New rider? With the APTC clutch in a 796, you should be getting a minimum of that...

Report back on your findings.

It can't be doing it much good, and your trans and engine share the same oil supply. If it's really the bike, swing by your dealer to make sure. Otherwise, you may need to learn the proper technique. Not that difficult.

i test rode a new 796, and when downshifting and blipping the throttle, the bike would hit a flat spot or kind of chocke. i remember my bike doing this before i had the termi exhaust and ecu put on.

At least on mine, that went away after ~ 800 miles. Could be disconcerting I agree.

It was a lot smoother up shifting using the blip method by felt the Same downshifting ill take it into the dealer and see if there is something wrong I hope it's just me.

(Update)>>>>!!!!!!!

I'm a tard.. I figured it out the although i was successful 5 out of the 10 down shifts I still did and obviously will get better at it since I have to down shift !! 200 more miles till the Termignoni's are going on!

It's a learning process - you'll get there.  waytogo

My 900 taught me a scary lesson about down shifts the first time I really got it out. I had a 620 before that, with it's semi slipper clutch one could drop a couple gears and dump the clutch w/o issues. I did that on the 900... and near pooped myself. The 900 doesn't have the APTC clutch in the 620, 695 etc. Just a normal one and I locked up the rear wheel briefly coming into a fast sweep at about 50 mph. Tire chirped, bike bucked, I ran onto the double yellow before recovering... Lesson learned! Or at least noted. now throttle and clutch management are part of the norm for me when out for a ride, but it was something that I had to work at.

Yes, that dreaded " flat spot!!" It occasionally shows up coming from 5th down to 4th at one time I thought I had blown my transmission!!!
