CB350F Rear Shock Replacement
« on: December 22, 2025, 02:50:16 PM »
Hey y'all,

The rear end of my bike is the bounciest I've ever felt - a real pogo stick.

Looking on 4into1 and other websites there sure are a lot of options out there. Earlier this year I got burned on some cheap ebay shocks for my CT90, they only lasted about 100 miles before letting all the oil out - I'm trying to avoid that experience again.

Chrome would be nice, damping adjustablility would be nice, dual spring rate might be nice...

Anyway, I was wondering if y'all had any go to options, or what you like best?

Thanks!

Hagons are good, they work well, last well, and aren't as expensive as some. Also, they can supply them with springs to suit your weight/pillion/luggage

Never heard of Hagons until now. I like that they seemed to be speced to the bike whereas the ones on 4into1 claim to fit a ton of different bikes.

I might have to ask Santa for some  :o

I replaced the rear shock on my Suzuki Bandit 1200 with a very inexpensive JBS (Jap Bike Spares) shock, and it's actually not bad!

The JBS one actually looks quite a bit more premium in your case. The ones for the 350F don't look half bad either.

Man it's hard to know with suspension isn't it? Between the Hagon, JBS, and 4into1 shocks you'd have a hard time telling a difference other than price. It's not like these manufactures are posting spring rates, suspension dyno graphs, bushing tolerances, and seal data. So what do you do? Go off of reviews I suppose, but that's hard too because 99.9% of people only reference the shocks they bought and the blown up shocks they're replacing. It certainly makes it hard to justify spending twice as much for name alone.

I disagree. I don't know about JBS, but I got some for a 750 from 4into1 and they were mush. Pitted almost instantly too.
The Hagons are definitely a good step up from any "stock" type shock. Plus they're customizable.

The cherry would be a set of period correct aluminum body Konis.

Sorry, what i said wasn't clear. I meant just based off the pictures and descriptions on the websites. I'm sure they ride different and age differently hence this thread.

I wonder if the 4into1's were mush because they spec the same shock for the cb350 twin as they do the cb750 lol

I would love some Hagon's but man is $440 delivered hard to swallow.

I'm throwing around the idea of try to fit the stock springs onto adjustable dampers. I figure that might give me the right spring rate and damping

Basically, shocks that work good and last require better materials, engineering, and a lot of good machine work.  That's all expensive stuff.  So, in general, just like a lot of other motorcycle parts, you get what you pay for..  Just be realistic with yourself about what you really can use and that should help keep costs under control.
If it works good, it looks good...

Ah. Yeah, agreed 100%.
That's wild that they'd spec the same unit for both bikes. I started out buying from vintage CB and 4into1 and such but quickly found their products to be consistently subpar and ended up spending more money than I care to think of at CMSNL and Yamiya. The cheap stuff works just fine in most cases but I was doing a full resto w period correct mods on a bike I've owned for more than 30 years that's now insured for 20 times what I paid for it in the '90s. Lol.

Man the IKONs look nice, I like the adjustability yet stock look. Quite $$$, but not quite as $$$ as racetech or ohlins.

This is true, however it gets hard once you've been betrayed by "name brands" trying to pass inadequate garbage off as quality. In a world of re-branding, drop shipping, and "assembled in USA" my trust has been broken on the: spend more to get more model.

Yeah, I've had my fair share of reproduction crap, like condensers that only last 40 miles. I love Yamiya and CMSNL, but boy do they make it easy to spend more money than you paid for the bike. Not that i object to that behavior, but my wallet sure does!
