As some of you may know I had a mild highside not to long ago. This minor get off cost me major money, and I'm still not finished getting my bike to normal. This thread is to give you fair warning about the poorly choosen mounting point of the rightside Sato frame slider. This mount will not take a strong hit. Granted my bike did not have any sliders on at the time of the accident. It did how ever impact exactly where this slider is mounted. I don't have any doubt a good impact on this point will cost you a new head. That's $1,500 dollars for the head alone from Ron Ayers. Thats's not including labor installing head, or swaping the mechanical componets from the old head. I'll let the pics speak.

Very sorry to hear about the extent of the damage & cost of the repairs. However, I think everyone's crashes will have different dynamics and I've never seen a frame slider crack the head of the 10R because it was there. This is the 2nd post I've seen where a head was cracked without having sliders. When I crashed my 10 @ the track, I had Sato frame sliders on it. The bike lowsided into the dirt (LHS) at 140mph and endo'd after the rearsets dug into the dirt. The right side sato frame slider was snapped off semi-clean, with zero damage to the head. The remains of this bike were even in a couple of races this year. Then again, the dynamics of my crash will be slightly different from everyone elses. Having had this experience, I would not hesitate to put sliders (even Satos) on a track/race bike. I'll gladly replace bodywork, rearsets, clipons, & subframe over engine parts.

So you crash, NO SLIDERS but warn everyone about something you didn't have coz you THINK it may do something? Hahaha Oh that's gold. How about you warn us all after you have crashed (I hope you don't crash ever agin, but for the purpose of this) WITH the sliders and THEN tell us what DID happen, instead of what MIGHT.

This is the first i've heard of heads cracking. Sorry to hear about this. Are you going to tear the motor down yourself to help cut the cost down.

The point is this mounting point is not strong. I was barely going 30 mph win my back end steped out. The mounting point has no strength behind it. If you ever take a ZX-10R engine apart you would no what I mean. That area is where the cam chain runs, and it's hollow. It's not as strong as say the corner of a engine case supported by the frame. The ZX-10R doesn't use the engine top end as a frame stress member like most bikes including the 04 ZX6R. All I'm saying is you do not want this area of you bike to have a impact at all. Never mind it being a impact focal point due to a slider being attached to it. Your better off with something like a champ slider that attaches to a beefier part of the engine case, and the frame. Sato sliders attach to a bracket, and directly to one of the weakest points of the engine. There is only so much a 1/4 of alluminum is gonna take. Especially when it was never design as a stress member.

:+1: as birdman might have allot of knowledge about motorcycles I don't think he owns a 10 and working on them from time to time doesn't make him an expert on the 10. Don't get me wrong birdman, I questioned when I first read SP8s thread, but the fact that I own a 10 and been all over the the frame then I realize what he's talking about. Just my .02

I'm kind of on Birdman's side here. Maybe I'm a little confused so please correct me if I'm wrong as I was planning on getting the Sato's.

You had an unfortunate accident, without the Sato sliders and cracked your head. However you surmise that if you had the sliders, they would have cracked your head?

Do you have or have you seen a set of Sato's mounted on a 10R? Or is this deduction from their website photos?

Thanks for the pics SP8 and you are absolutely right about the placement of the sliders. I am horrified that anyone would even think of putting a slider on those threads! If I had sliders there I would remove them immediately as even a tipover could split the head.

The Champ / Muzzy slider have the right idea in my opinion, as they not only have two mouting points but are on relatively strong areas on the frame. There is no way a slider can guarantee no damage in any situation but after seeing the mountings of several slider options, the Champs look like they'll take the most abuse.

Before doing the offset sliders I was looking really hard at where to mount a standard slider. Tho location where the SATO is mounted was a first option. However, looking at the mounting post/plate behind the alum bracket I could not see it holding up. If it were to fail, then your putting the load directly onto the head. A better location is up and towards the back on the same bracket. It mounts to the frame. A more solid mounting point.

Expressing a concern is legit as the mount point used in the shown SATO setup may not be the best. If I had the SATO's I would use the mounting point I described above.

Remember every crash is differrent and you cannot 100% predict what will happen. SATO has a good rep from my observations. Its just the mount local that should be changed IMO.
