Frame slider - Ducati.ms

Has anyone put this on your Hyper? The instructions mention having to shore up the engine while installing, is it worth the effort? The forks, rear and bar ends were easy in comparison. Trying to decide if I should return them or not...thx.

If you push the new bolt in at the same time you pull out the original you won't have a problem.

It's not a bad idea to put a jack under the engine, just to support the weight a little bit while you install the bolt.

After you remove the nut on one end of the engine bolt, start raising the jack little by little, while turning the engine bolt at the same time. You can feel when the bolt gets loose. Leave the jack in that position, and the bolts will slide in and out easily...

Great advice. Thx.

That's the way I did it.

Plus, I tested my bike in a full crash. The axle sliders were untouched, only the frame slider was.

It looks like I had some good luck today, put a jack under the bike with just a slight bit of upward pressure and the engine bolt came out with zero resistance, the rest was a piece of cake

Looks like the frame slider could save your leg in a low side.

Let me throw some caution to the wind. I was considering frame sliders and was told that there were some potential issues. Depending on the severity of the fall, the frame sliders can actually act as a lever to tweak the frame, a very costly repair if not not a total. Also, I heard of a cracked engine case caused by the rod flexing as a result of frame slider.

This information came from a very reputable shop who works on a lot track bikes.

most frame slider kits for ducs come with a strengthened motor mount rod that is an improvement over stock. Your argument is common with just about any bike. Every time my frame sliders were used on various bikes (4 times now), no levering happened and they saved the bike from much more severe damage. That being said, frame sliders causing more damage can happen and has to some people. Of most of the instances that I've heard of, there is no indication that the damage would've been any less if the slider had not of been installed prior to the crash.

I have them on every bike that I own.

I even have a muffler slider on the termi from here https://ssl.perfora.net/www.advanced...dex.shopscript

I have them as well. That said, as an engineer, I can see how they could bend/break the frame in a crash. Sliding on a smooth surface, like a track, no problem. What if the bike is sliding and the slider catches a crack in the pavement, or a drain grate, or anything to stop it? All that energy goes somewhere, and that is the frame. I have the RJS sliders. There is a steel base that mounts to the frame/engine mount. The plastic slider then bolts to that. I would tend to think this design may be safer but only testing would tell. Based on countless dirt bike crashes of all kinds (some bad) I tend to think the best sliders for the Hyper are a good set of handguards on quality bars. If the bars stay intact, they will hold a lot of the bike off the surface of the pavement.

If the bike goes down that hard you have more to worry about than that slider damaging anything. For me, living in NYC, they are a necessity. My Monster had been dropped by me and slid with no issue and the numerous times being knocked over while parked that damage was minimized.
