I have a full set of Pit Bull stands for maintenance as well as long term storage through the winter. I keep my bikes on front and rear stands to prevent flat spots on the tires, a recommendation I got from Michelin's website.

When I first put my Grom up on the rear stand, I notice immediately the the Grom was sliding backward on the stand like it was just going to fall off the back. My fix was to build a 2X4 "T" which works both with the rear only and with the front as well.

For use as a rear only, the block up front prevents the slide rearward when the front tire bumps into the block/chock.

When you lift the front as well, the block no longer prevents the slide, but the top of the "T" makes contact with the wheels on the front Pitbull preventing the same rearward slide.

Thought I would pass this info along for others to use whether they use Pitbull or other brands. I imagine this issue is not just with Pitbull stands. The last thing I want is to go to the garage and find my Grom on the floor beside the stands.

If you added rear spools such as the Yoshimura, you will not need the brace.

do you really think it going to get a flat spot? the bikes not that heavy and how long are you storing it for? a year?

I store my bikes lifted for about 4 months out of the year through the winter. I use fuel stabilizer and a battery tender on both bikes. I have the stands, and it takes me 30 seconds to use them, so why not? It is not good for the tires to sit in the same spot for extended periods of time.

My original post was a heads up for folks using the Pitbull rear stand. I was trying to give my felow Grommers a heads up of the potential for a tip over.

i would not lift my bike using the yoshi stand stoppers,

i installed them, the only thing that secures them to the swingarm is a tiny screw that is maybe 3-4 threads deep, and the location of the screw is not really engineered to support the entire weight of the bike when its on the stand, its just on the bottom side.

For example when you actually tighten the spool on the yoshi stand stopper all the down to a good torque, you can actually see the stand stopper flex inside the swingarm - its that much of a POS - horrible engineering design.

all my other bikes when i put them on the stands, i have no problem bouncing up and down on the bike when its on its stands, with the Grom on the pitbull stand using the yoshi stand stoppers, it feels like the bike will snap right on the spool stands if i did that.

Good to know! I figured there was a good fit and the weight would actually be supported by the short block that slides inside. Guess its not snug enough and the screw is bearing the weight.

I know what you mean about sturdy stands. I can jump on my Versys on its spool stand, and I can jump on the Grom on its rear stand. Without the brace I made, It would simply slide off.

Thanks for the reply!!

Are you sure you mounted it correctly?

mine is mounted correctly, go ahead and take a picture of the screw and then ask yourself would you really support your $3k bike on a spool that is held by 3-4 threads?

you are correct if the standstoppers was a press fit, but it was so sloppy in mine that the only thing that tightened it down was the small tiny screw they provided, since the block itself has slop in it when sitting inside the swingarm, guess where all the weight is going to load up on, that tiny ass screw

if yoshi designed the screw #7 that locks the standstopper to the swingarm, to go through the entire stopper block and both sides of the swingarm, it would be alot more robust versus just having a few threads in there only on the bottom side.

The milled block sits INSIDE the swingarm, so I'm not sure where the 3-4 threads you're talking about are. The Yosh piece distributes the weight to the very back of the swingarm.

Yours has slop? Mine was a very snug fit - had to tap it to get it to slide all the way in. Maybe you got an earlier model and they've fixed this?

If the screw you're talking about is that tiny little one with the hex-key opening on the head, you're right - I wouldn't trust that bolt to hold the bike, but I'm surprised your spool blocks have any slop.

i bought mine like literally in september last year, mine had crazy slop, like i said when i torqued the spool down to their spec, i saw the yoshi standstoppper flex out of the swingarm from the torque.

so........ if it was a press fit this issue is nonexistent, mine was definitely not tight at all until i put the tiny screw in.

but maybe yoshi fixed this, but for me im not trusting them to lift my bike with them,

Contact them, see if they'll swap it out, in case you got a lemon?

Be worth a shot, instead of having one that doesn't work.

Any idea why only the Pitbull would exhibit this behavior? I'm about to try it out myself with my Pitbull stands to see for myself but don't understand.

I also got a cheap trackside rear stand as a backup and the difference I see is that the Pitbull has a round support thingy where the trackside is square. I rather use my Pitbull so I can return the trackside and save some money.

The Grom definitely needs a better solution for a Spool/Slider combo. If I ever tear down either of mine and have the swingarm separated I'm going to either do a 6/8mm weldnut or with the Composimo Stretch Grom get the Composimo arms drilled and tapped for a 6mm bolt. Still have to sort something viable for the front though.

I need to use it to remove the front wheel. I think if I use my pitbull at the very end of the swingarm and have the arm sit against the nut it should stay put.

I'm a bit worried cuz I'm doing this in my living room and if the bike falls it's going to mess up my wood floors too.

Its funny to see people get so paranoid about something, that they cause more problems than they solve, as you found out :D The GROM has 125 pounds weight on each tire, and you are storing it for 4 months. Did you ever even think to just go out and push the bike forward or back a foot, once a month ???? Probably too easy and simple a solution for you...

FUEL STABILIZER: Ethanol fuel is HORRIBLE when it sits, even with stabilizer, 4 months of that could be very bad. What would have been MUCH BETTER is non ethanol fuel, it was just 4 months, non ethanol fuel would be 10 times better, even without stabilizer if the tank was completely full.

You had the right idea, it is funny that you just did everything wrong...

You know, I always wondered what the Groms weight distribution was and now thanks to JetPilot never posting incorrect information I now know it has a 50/50 spread and also weighs 250lbs, not the 225lbs that Honda says.. Thank you! I'll be correcting the weight in my owners manual
