Do you guys have a part number from the box??? Also why does tyga sell these at over $400 a pop and kingkong is $179 somthing doesnt seem right?
Sorry, I tossed the box.

There seems to be at least two of these type/size shock from YSS. I got the budget one with pre-load adjust only. The one Tyga has is fancier.

That is true. The one Paul sells is fully adjustable. I also got the budget version with pre load adjust only.
 
I believe the stock is 245mm.
 
Yeah 245-250 depending on your degree if error in measurement.

I'd like to see a more down to earth way of mounting a more common 270-280 pit bike shock there.
$500 for a tiny coil over shock is tough to swallow.
 
I purchased mine from Bikerz Bits (YSS G PLUS FOR HONDA MSX 125) and installed it today. I'm impressed with how much better it rides.

I did the installation by myself without any issues using cargo straps to get the bike off the ground once the bolts were loose. You'll need a 14mm socket, a 17mm open-end wrench and a torque wrench set to 34 lbf·ft (if you really want to do it right).
 
Just installed mine ... orange, not yellow, spring. Photos are misleading. Install went fine. I used the scissors jack on the frame with the side stand down and it worked beautifully ... soon the rear wheel could be turned and the support was essentially a tripod: front wheel, side stand, and jack. Hardest part was reinstalling the rectifier onto its bracket; it's very tight in there. I found that to adjust the spring tension, you just loosen the set screw on the upper adjusting ring ... and then reach in there with both hands from the back of the bike and just rotate the entire spring in its seats while keeping a finger on the upper adjusting ring ... it will turn with the spring as a unit in the desired direction. Much easier than working with the adjusting rod to turn the ring alone.

Had to remove the exhaust can to get to the set screw. I've got medium tension on it right now; until I get my fuel pump replaced under the recall, I can't try it out. It's very nice looking. Has spring tension only ... bought it off EBay from import_parts579 for $185 ... very well built shock/spring indeed! Eleven days to delivery and it requires a signature for receipt by USPS. Really stands out and looks good!

Part number: MC302-250T-19-7. The "250T" is the length in millimeters and it is just a smidgeon longer, but no problem. Just insert a phillips head screwdriver through the lower bracket after you get the top bolted in ... and angle it downward into the lower boss of the shock ... using the screwdriver to jimmy it and line up the holes ... and then push in the lower bolt from the other side until it pops the screwdriver out the other side. Remember to totally relax the spring before installing it, too ... makes it all a lot easier. Tighten to 34 foot/pounds.
 
Looks great, works great! I only have 100 miles or so on the shock but I'm impressed.

I think the shock is 250 long, and the bike does sit a bit higher. I would recommend to get a longer side stand for a little more confidence when parking, but it's not so bad.

Because it is longer, you need to run your chain a little slacker.

I have and have had plenty of big bikes and know a bit about setting up suspension however I am no expert! My butt dyno and just looking at it says this longer shock has longer travel, a softer more compliant spring, and better softer/smoother and more controlled damping. I got the preload only adjustable shock. I weight about 70kg/155lb and would say it's perfectly sprung and damped for me, but it also works very well with my wife 57kg/126lb on the back. You won't bottom this shock out unless you're a really big guy, and anyway there is a lot of preload adjustment if you need it.

It works great and for the price is an absolutely excellent purchase. Quality is top notch, materials seem well finished too, somewhat unusually for budget Thai gear.

I have seen these with black gas bottles and silver like mine, with and without damping adjustment, with and without a gas bottle attached. Not really sure what's what as YSS website is in Thai. There are apparently fakes doing the rounds. It's going to be hard to avoid if you are buying by mail order, except buying through a known supplier. You can use this guide once you have it in your hands:

In summary; if you're hoping to improve your bikes comfort, rideability, add some bling but not spend as much as Ohlins... then I'd say this is a good way to go. Gazit also make shocks in a similar price range, I have seen one up close but not ridden it, it looks good but can't say more than that.
 
For install I had the exhaust off anyway at the same time, and stood the bike up on a block and sheet of wood. It has a flat bottom on the engine and it's stable enough if you slacken all the big bolts before you get started, but be careful.

I found it annoying that you need to remove the rear fluid reservoir, to get to the regulator bolts, to remove the regulator bracket, to get access on the top bolt. Still, space is at a premium and I guess you'd have to call that an engineering compromise.

The shock fits perfectly in the mounting points but because it is a little longer, be sure you have lifted the bike high enough for it to go in!
 
In lieu of the supplied adjusting tool, I plan to get a 4" grade 8 bolt with a long shoulder and just hack off the threaded portion and put that into the tool bag. Not sure what the diameter is for the rod, maybe 1/4"? I also notice that the bike sits taller and it makes it harder to kick the right leg over my Pelican case on top of the Vagabond luggage rack ... and it leans over a bit more. I will probably need a plate on the bottom of my kickstand, which has already been lengthened by an inch. This bottom plate will probably be a bit wider than the kickstand foot .. just to add some security in soggy grass or loose sand. Honda needs to make larger kickstand bases for their bikes.
 
You can just grab the spring in your hands and turn it. Adjuster turns with. There is not space to use the supplied adjuster while assembled on the bike not even with a low exhaust .

It won't be imperial. I guess either 5 or maybe 6mm rod.
 
Yes, I know about the spring; I posted that earlier. Once the spring is preloaded enough, however, you need the tool because the reservoir prevents the hands from getting a good purchase on the spring. One thing: bend a 45 degree angle on one end of the supplied tool ... just the end of it ... and it'll work better.

Do you know if your shock was the real deal? did it have a code printed on the spring?
