Hello all,

I have a 2019 CB1000R with about 250 miles on it. I love the motorcycle but I feel like it does not shift as smooth as I expected. My previous bike was a 2015 Kawasaki Vulcan S and I never really thought about the smoothness of the shifting.

Some times when upshifting, the NSC "clicks" into gear very smoothly, and other times it takes more effort to upshift into gear, almost like "two clicks" to engage into gear.

There have been a few times while quickly upshifting that I have "mis-shifted" where the revs jump and the indicator displays "-" and then the transmission clunks back into gear after the revs drop.

Has anyone else experienced this? Is this normal? Will the shifts improve after the 600 mile service? Are my expectations too high? I have a notion that my expectations may be too high considering the Gilles Shift Holder aftermarket part was developed for "crisper" shifts. Perhaps this is normal and I am not used to this type of gear box.

Thank you everyone in advance for the help!

So I just picked up a 2019 today after trading in my 2014. On my 2014 clutchless upshifts into 3rd thru 6th is smooth as butter just like every Honda I've owned. On the 2019, several times while clutchless upshifting from 5th to 6th I got a false neutral. It may be related to my operating of the electronic throttle. On the 2014 I would just have to close it slightly. On this 2019 I may have to close the throttle completely. Still working it out. I'm planning on adding the Honda quickshifter. It's OEM on my 2017 SP and it shifts up and down like butter.

"On this 2019 I may have to close the throttle completely." Nope that isn't it. Check chain tension.

I watched them uncrate it today. It's definitely not too tight.

 

[BigOne-94-14]

I didn't say it was too tight. I said check it.

 

[philipdupree]

The shifting got much smoother after the first service. I also had to learn the correct technique to shift gears on a sport bike. I no longer feel like there is an issue with rough shifting.

Are you saying too slack would cause false neutrals with clutchless upshifts into 6th?

 

[BigOne-94-14]

Slack chain makes shifting feel like shit. Correct tension and shifting is buttery smooth.

Spec is 40mm - 50mm of slack on the SC80

 

[BigOne-94-14]

Yes and?

 

[Bevo]

Yes and?

That's very slacky compared to most. The consensus on most sport bikes is too much is better than too little.

 

[BigOne-94-14]

Did you ever check it?

 

[Bevo]

Did you ever check it?

Yup, it was at about 55mm. I just came from Wild West Motoplex (Katy, TX) today where I purchased the bike on Saturday to have the slack checked. It's a pretty big dealership with a lot of employees. I brought my C-spanner and asked them if they wanted to borrow it. (This is a different dealership than the last one that borrowed it) The service writer said, "yes please". Then the tech that returned the bike also thanked me for the use of the C-spanner.
So, after the chain was adjusted clutchless upshifting is a little more smooth, but again I hit a false neutral instead of 6th. This is only happening going into 6th and not every time. Pretty exciting when you're trying to merge with 75mph+ traffic on I-10 and you hear the revs jump and you have no acceleration.

Here's a list of new bikes I've purchased just since 2009:

2009 CBR600RR (sold)
2009 CBR1000RR (sold)
2010 CBR1000RR (sold)
2012 CBR1000RR (sold)
2014 CB500F (sold)
2014 CB1000R (sold)
2017 CBR1000S1
2019 CB1000R

I've never had a false neutral on any of these bikes except the 2019. Now, if I've been on a riding session and haven't been in 1st for an extended period of time, when I pull away from a stop I'll occasionally hit neutral instead of 2nd, especially on the 2017 (QS) because the upshifts from 2nd thru 6th are short and effortless and muscle memory forgets about the long throw from 1st to 2nd.

QS and heated grips are on order. Hopefully the bike and QS will play nice and eliminate the occasional false neutral.

I've got a 2018 with the QS. False neutrals are not uncommon between 5 and 6 for me. Still like the bike, just know I need to be deliberate up there in the upper gears.

 

[PiersD]

I have the quick shifter on mine and I get the occasional false neutral between 5th and 6th fwiw.

My QS is on order. I'm just making the shift from 5th to 6th very deliberate, not unlike 1st to 2nd.

I’ve experienced this exact issue and the dealer wasn’t able to remedy.

however, when I installed the quick shifter all of those issues you described have vanished even when using the clutch.
I suspect the shifter didn’t have the correct measurements dialled in and it was fixed when I installed the quick shifter using the measurements provided in the instructions.

I don't think it's the shifter, it may be a case of the slots and dogs having to be worn in. When my tech installed my QS, he would have remarked if the OEM shifter was not aligned properly.

No offence but I think it would be a better description to say the slots and dogs are wearing out.
When first assembled the insides of the gear box are exactly as they should be.--This is precision engineering here. All that can be achieved through use is wear.---Pistons, rings and bore wear in.

Yeah, but when you have the issue on the same day the bike is uncrated, and it goes away over time, how would you explain it? I got several false neutrals only from 5th into 6th. The bike hit 600 miles last Friday. I'm far from being a noob. These are the brand new bikes I've purchased just since 2009 alone:

2009 CBR600RR ABS
2009 CBR1000RR ABS
2010 CBR1000RR
2012 CBR1000RR
2014 CB500F
2014 CB1000R
2017 CBR1000S1
2019 CB1000R

Only the 2019 had this issue and I don't recall folks on corresponding forums with the same shifting complaint.
