I want to install frame sliders: Difference between revisions

'''They look cool, and I still want them!'''

Some Polynesian tribesmen believe that beautiful bird feathers can also make a man look beautiful. The men pierce their faces and wear the colorful feathers like jewelry... Well, I've digressed here. :) If you really want frame sliders on the EX250, they CAN Be installed.

If you really want frame sliders on the EX250, they CAN Be installed. Their usefullness is unproven, and considered by many as purely cosmetic.

Jim Race did some thinking and sketching. Here is his design:

Someone posting under the nom de plume "Mibgebert" has ~~actually implemented this design~~. Here are ~~the details~~:

Someone posting under the nom de plume "Mibgebert" appears to be the only person who had gone through the trouble of installing frame sliders on EX250. His design has some obvious flaws, though. The sliders are manufactured out of solid steel and have sharp edges. They will not absorb any shock, and will transfer all the energy directly to the frame, potentially doing more harm than protection. Also, the sharp edges may not slide well, "biting" into asphalt and acting as pivots, again, causing damage. To some extent these two issues can be corrected by adding plastic(?) tips for better energy absorptions and sliding.

Here are some photos of Mibgebert's frame sliders:

This design generated some controversy. Here is a [http://forums.ninja250.org/viewtopic.php?p=164083#164083 link] to the original discussion.

~~Remember~~, that stock turn signals will come in contact with the ground first, ~~so your frame sliders will be useless unless you replace stock turn signals~~ with flushmounts ~~first~~. ~~Please note~~ that frame sliders can pose danger if installed incorrectly. They can potentially bend your entire frame in a crash. The frame is designed to withstand certain forces, applied in certain directions at certain points. Load-bearing parts (e.g. engine mount points) ~~of the frame~~ are very strong, but other parts are weaker. If you simply bolt a frame slider to a random point on your frame, all the energy of a crash will be transferred through the slider to that point. Is the frame strong enough to absorb all that energy? Will it bend? Will your mount point break off? Remember, that EX250's frame was never meant for frame sliders, and the above mentioned designs are unproven. Think, before you install.
