There's a huge difference between buying some Chinese rearsets and installing Chinese brake levers. If tolerances are measured in the thousandths of an inch, never buy Chinese. Like you said, you get what you pay for. Anecdotal evidence of surviving one crash is NOT valid evidence.

OP, have you tried talking to a CNC machinist? Take an old set in, scan it, mill it. How about checking out some junk yards?
You've never seen OEM Suzuki parts fail?...Like footpegs snapping and cracking clip ons.

I have.
 
I know my old gsxr1100 stock footrest brackets broke just from putting hi loading thru them to assist turning, I made up some from thin s/steel to solve the problem, no such problems on present Suzuki gsx-s setup
 
It's possible for any part to fail, but it's way more likely with cheap Chinese stuff. The 200 dollars you saved won't feel so good when said part crashes your bike or leaves you stranded.

No doubt, I was just pointing out that it doesn't necessarily have to be cheap in quality because its Chinese or even if costs less than some of the often overpriced genuine OEM parts or those from well known brands.

I tend to buy direct from a manufacturer and its not the lowest end you get from China.
 
I have noticed that China manufacturers in general have raised there standards considerably over the past 30yrs that I've seen.
I have a Chinese car hoist in my own garage, I've had a Mitech inverter mig welder for over 10yrs, its never caused me any problems, i have some chinese radiators on my xr650r, that being said I used to have nothing but problems with some old Chinese made motorcycles, that were imported without back up parts.
the really cheap and nasty stuff has moved to places where labour is cheaper
 
I recently purchased a M4 gp slip on and it doesn’t have the springs. I contacted vendor and it wasn’t sold without springs because it was in very good condition not new. Just meant it was missing the springs but still brand new. Does anyone know the size of the M4 spring I need or where to purchase them. I have looked everywhere I could think of. Thanks.

Hi and welcome to:
"This is not your topic, nor even relevant to the questions raised in the OP"

As for those springs, contact M4 directly, they were quite helpful when I talked to them over the bolt used to hold the baffle
 
Per the M4 web site:

Replacement Parts

Midpipes, Muffler Sleeves, Spigots, Flanges, Brackets, Clamps, Springs and so on.....
Please Call For All Replacement Part Needs

It includes a bill of materials and there's no spring(s) in it. At that point I have to ask - What Springs?

....and for those contemplating those "cheap Chinese levers" here is the intrinsic problem with them that most uninformed rider never actually think about. The pin on the end of the MC piston that sits inside that little hole in the lever needs to be able to "float" as the lever goes through its range of motion, and that's the problem alot of those Chinese levers cause. They may LOOK similar to good quality aftermarket name brand levers.....but they don't work the same.

Brian gets into the nitty gritty of it around 4:30




The thing about Chinese knockoffs is that there's no quality control. They reverse engineer something and out of 1000 unit they manufacture maybe 500 of them actually come out OK and are somewhat useable, by the remaining 500 will fail because they have no QC. For a reputable name brand a 50% failure rate is absolutely unacceptable. For a no-name knock off company on the other side of the planet that you purchased through eBay they don't care because you likely can't sue them when the part fails.
 
While I love me some cheap chinesium things, I would never get knock offs for vital parts, such as brake components. Motorcycle (and most vehicles) brake systems are quite simple, it doesn't need much to go wrong for them to stop working... So what little parts are there should be top quality.

As for controls, I feel the same, there is no way any cheap copy is as good as a Japanese made OEM part.

I stick to OEM till I can afford some fancy non copy items.

The 2011 - 2019 M4 slip on comes with two springs that hold the slip on to the cat Incase the clamp fails.

Sorry about that. I’m new and can’t start my own topic yet. I just saw aftermarket part and figured this was a good spot. There is no general exhaust topic made yet. Once again sorry about that.

Well, call me stupid, I bought a set of Arashi rearsets

These things having traceable brandnames (aka Area 22 and Kemimoto), and finding no results for these things failing on people,
plus the fact hotbodies tries to con people into paying $340 for them, I figured I'd take a chance

$134 delivered at the door

So, initial impression
Nice box, nice parts, as is, these things surprised me
the only things I considered suspect were the bolts used to bolt the rearsets to the frame (black, grimey, as if oiled then left on the shelf for ages),
looking rather low quality, probably would be rusting pretty soon, I already decided not to be using these (OEM bolts don't fit though)

It did have the ability to mount the OEM brakelight switch, but since I replaced my brakelines a while back already with the knowledge I would be replacing my rearsets
and that aftermarket often times do not have this option, I already had a pressure switch installed
Luckily, the OEM brackets for this feature can be removed

Installation
For starters, locktited the beejezus out of them (truth be told, I'd do that with any rearset)

Left side first:
Turned out I received the wrong shiftrod (for a 750 k6/7), which works with the knuckles threading into the rod, while the 1000 k5 works with the rod threaded into the knuckles
I could use the knuckle in the set for the gearlever, but not for the engine side, where I couldn't replace the knuckle
Me, not unbeknownst to improvising, got a length of thread and inserted it into the knuckle, then I could screw the rod on

That problem solved, I ran into another problem: The gearlever didn't clear the shiftrod
I ended up drilling the thread out of a couple of nuts and using them as spacers beween the rearsets and the frame, also put a washer at the gearlever knuckle
IMO, even if I had received the correct shiftrod (which would have been just a thin threaded rod, not an 10-8mm thick bar) , I'd still have to shim the rearset, though I could've probably left out that washer at the lever

Luckily, the position of the rearset and angle of the gearlever were correct from the get-go, I had room to lengthen the shiftrod, but already being at the furthest back/highest up
I would have little to no play in shortening the rod, if the lever was set too low

The right side:
Again, shimmed the rearsets by using a set of drilled out nuts (done for equal spacing as the right, not because of any clearance issues)
I did put a washer between the brakelever and the connecting rod to the brake cilinder, since it pulled the conrod of the brakecilinder outward and put pressure on the circlip
Just mostly a PITA setting the brakelever angle, but that also had to do with the lousy way you have to change the length of the brakecilinder conrod on Suzukis

To limit brakelever return, there's also a concentric post, but the lever was too far outward for this to have any use
(Aside from setting up the brakelever angle correctly totally negating the use of this post)

As it is on the bike:
Would have loved to have seen a sunk bolt on the lower brakecilinder hole, since the heelplate is spaced to clear it (using a bolt-in-bolt attachment for the heelplate....don't ask why),
making it protrude in a way it's noticeable at my right foot
And it does have some flex, which makes me wonder how these things are gonna hold up when a lot of weight is applied to them (luckily, I'm a scrawny dude at 143lbs nekkid)


The only thing I had to do when all was done was make a mounting plate for my brakereservoir, since these rearsets moved it 3 inches back
(and I went about an inch up)
