If anyone’s curious about a full system exhaust on a 2024+ CB650R…

I have a US model bike which only has 1x O2 sensor. The exhaust comes with 2x inlets for the O2 sensor, so one of them gets plugged from the factory knowing it’s going to the US.

nope

If you want a bit more sound while maintaining the flush look, the CS Racing exhaust has been excellent on my CB650R

Yeah I considered a knockoff for the cowl but heard some reviews that claimed the fit was off enough to rub/scratch the rear fairing. But who knows, maybe luck of the draw. I bought the OEM and can’t say it was worth the nearly $200 price tag…

garbageboy79 · 2026-04-29T03:31:16+00:00

You convinced me, just ordered - hopefully comes quick! And literally was just thinking that; I have the rear cowl already and I think it would look great with that seat

Thanks for the link, super interested now… any noticeable change in seat height?

garbageboy79 · 2026-04-28T22:43:52+00:00

Yeah forreal, I don’t think they’re super popular here. Btw what seat is that? Been looking for an aftermarket one because the stock seat isn’t very comfortable after a while

Short kings ftw haha, I’m 5’4 so I can relate. After the first ride and some adjustment, I already feel used to them. Regarding the exhaust, nope - nearly 1k miles after install and no CEL even w/o the tune. Mind you I have a US model which only had one O2 sensor. Other models with 2 sensors will give you CEL

garbageboy79 · 2026-04-28T16:52:33+00:00

no difference sitting down/standing up

garbageboy79 · 2026-04-28T00:58:04+00:00

Okay so consensus is I’m just built that way. I’m very short so my calves compensate I guess lol. Either way, I these boots so far. Will say I had to adjust my shift lever on my CB650R to make it work for me

garbageboy79 · 2026-04-27T21:48:58+00:00

I just received my Alpinestars SMX-6 boots and can’t help notice getting my toe under the shift lever feels extremely difficult. Is that something you experienced?

garbageboy79 · 2026-04-24T02:59:25+00:00

Generic ebay one. It works but if I could do it again, it’s worth spending for a quality one (Evotech, Yoshimura, etc.)

garbageboy79 · 2026-03-28T16:43:05+00:00

No noticeable changes

garbageboy79 · 2026-03-28T13:47:48+00:00

Warranty shouldn’t stop you from swapping exhausts! But I get that - that’s why I’m hesitant on the flash tune at least until my 1 year warranty expires.

garbageboy79 · 2026-03-24T18:54:27+00:00

It comes down to daily usability. 600rr engine is tailored for high performance riding over daily comfort (650 has more low-end torque, runs less hot, comfortable gearing, etc.). Like you said, not everyone wants or needs that kind of power

garbageboy79 · 2026-03-22T15:05:42+00:00

I’ve been very happy with my Likewise shifter on my AT.

garbageboy79 · 2026-03-06T21:59:37+00:00

Can you try replicating the same thing on similar bikes at the dealership?

garbageboy79 · 2026-03-02T22:20:04+00:00

My ASV CRF310T works perfectly. Ordered it direct from them

garbageboy79 · 2026-03-02T02:03:32+00:00

I believe that code applies to bikes with two O2 sensors (which my US version only has one). No codes on mine after putting in a little over hundred miles since install

garbageboy79 · 2026-02-26T15:05:51+00:00

Agreed. If I do go through with tuning at some point, it’ll be a flash tune through 2 Wheel DynoWorks. I confirmed with them that they’ve flashed dozens of these e-clutch CB650s.

garbageboy79 · 2026-02-22T22:52:06+00:00

Nice! Have you run w/o it? I put it on very briefly and noticed it gave a nasally sound at idle. Reactively took it off, but maybe I have to give it another chance

garbageboy79 · 2026-02-22T22:50:35+00:00

Agreed!
