I'm not sure this is my SE5 just settling in after the initial running in period so this could now be a normal characteristic but the change up has somewhat of a thump to it. I'm fairly certain is was smoother previously. From what I understand of the SE5 system, it drops the revs when throwing the gears in so that the transition is smooth, and does this regardless of where the throttle is positioned. This should mean smooth syncing but at present there is a definite jolt as it moves through each gear. Downshifting is fine.

There were many reasons for the change of the site software, the biggest was security. The age of the old software also meant no server updates for certain programs. There are many benefits to the new software, one of the biggest is the mobile functionality. Ill fix up some stuff in the coming days, we'll also try to get some of the old addons back or the data imported back into the site like the garage. To create a thread or to reply with a post is basically the same as it was in the prior software. The default style of the site is light colored, but i temporarily added a darker colored style, to change you can find a link at the bottom of the site.
SE5 gear change thump!
- Thread starter jetskier

I have about 5200 miles on my SE5 now and it still shifts smooth. The only gear i get a thump in is when shifting into first. All other gears are very smooth as long as i'm at 3500 RPMS or more when shifting. I would get the dealer to check it out as the service bullitin for shifting issues might just resolve this problem for you.
I have found that if I roll off the throttle slightly during upshifts it is alot smoother especially from 1st to 2nd and 2nd to 3rd. I dont roll off between 3rd to 4th and 4th to 5th and it is smooth enough. I try to shift above 4000 rpm but thats not easy when crawling along. At speeds of about 60 to 80 k/ph (37 - 50 mph) I dont use 5th gear and prefer to leave it in 4th. After that I shift unless I'm hauling ass in which case I shift near the redline. I have seen 190 kph (118 mph) on the speedo so far! Hope this helps.

I have the SM5, not the SE5...but, you should lay off the throttle when changing gears...
For anyone who has driven a manual car, it's best not to destroy your clutch by hitting or staying on the accelerator pedal when you want to change gears...you'll kill the car...the same is likely true for the SE5
The SE5 is not a 'true' automatic...it's just doing the clutching for you...
I'd stay off the throttle...it will make for smoother gear changes...

I never roll off the throttle if anything i'm giving it more throttle. The standard shifting of the SE says to maintain throttle that there is no need to roll off. Were most of the problems i have seen come from are if the RPMS aren't high enough to keep it over 2600 after shifting it will confuse the computer till you give it more throttle causing it to lug the engine a bit. I usually shift at about 4000+ RPMS but never less than 3500 RPMS as i've found this is the shift point that confuses the computer were you want it to upshift and the computer says no its time to downshift.

In fact I shift around 6,000 rpm and don't roll back at all. I have been up higher if want to accellerate, but between 6 - 7K is the usual. Mine has been smooth shifting, but I've only got about 3,500 km on my Spyder so far. Remember there is a 9,500 redline. 5th gear is an oddity - <BAG>
This is true for the SM5 but not the SE5. The SE5 isn't a "true automatic" but when you press the upshift it automatically disables the throttle(as if you rolled off yourself) for a fraction of a second. This is noticible if you ever try to **** it at to low of an RPM and freak out the computer when it drops to around the downshift RPM.

actually, with the se5, it momentarily kills the enginge while shifting, just like an air shift..there is no need to lay off the throttle...actually it shifts more smoothly by Not rolling off the throttle.

ok....maybe i should actually read ALL replies before i add my 2 cents...seems others beat me to the punch...myapologies

fyi for the SE5 u do not roll off the throttle when shifting u just shift and motor on down the road

Interesting...so switching gears automatically cuts the throttle...good to go on that...

At my factory demo ride, the BRP guy told me to upshift at about 4000 rpm - I have done this ever since I got my SE5 and it shifts smoothly with no letting off the throttle.
The sweet spot seems to be between 3700 and 44400 rpms - shift other than in this range and I get the hard shift/clunk/thump.

I have to agree that shifting at 4000rpm is about the sweet spot, and now I've gotten my ears tuned to do this almost without looking at the tach.
Now can I ask a new related question. Hoping someone can enlighten...
I plan to get a trailer for my SE5 this summer... (Big roadtrip to Yellowstone N. P., Black Hills)... and was wondering if the shifting with a trailer pulled behind is going to make a difference on when to shift. Obviously, pulling an additional 250 lbs - 300 lbs gross wt. means more strain, but what about in shifting? And what about downshifting manually instead of braking and letting the auto-shifter downshift at about 2200rpm? I feel that keeping the rpm's high will be better when slowing down in traffic than allowing the machine rev down to 2200 rpm's.
(Example: You are travelling 55mph at 5000rpm, and come into a small town with 35mlph speed limit. You roll off the throttle and the bike starts to slow down, the bike starts automatically downshifting as your rpm's start to decrease. But I feel it might be better to watch your tach and at about 3300rpm downshift manually so that if you have to suddenly accelerate with "the trailer load" you don't put strain on the transmission.
I guess what I am saying is that with greater load to pull, keeping higher rpm's can reduce wear on the transmission. In other words, using more braking power of the engine (by downshifting) would be better all around.
Obviously, I'm not an engine guy, but logically this seems right? or is it wrong? :dontknow:
