Like my earlier fender mod on the N650 (
link to thread), I carried out another mod job. We all know how important frame sliders are for super bikes/sports bikes. After the purchase of N650 I was in search of a suitable pair of frame sliders which will not only save my bike if fallen but also save my leg in case it falls on me. After days of searching couldn't find any frame slider which could fit my requirement. Every pair that I saw was smaller in length. I would have fit those frame slider anyway but there was on major reason to walk away from those. The mirrors on N650 are installed on the fairing and they come out much further than the width of the handle itself. So, if ever the bike falls on its side, mirrors would do the first contact with the ground. This would result in either the mirror stem getting broken or the fairing taking the toll of the impact.
To tell the truth the previous owner of my N650 has once fallen the bike and there is a crack on fairing along the mounting points on the mirror. So to be on the safer side and avoid such type of incidents I wanted the frame sliders to be long enough in avoiding the mirror contact with the ground.
Alas, I did not find any such pair of frame sliders. So I finally decided to make one for myself.
To start with the basic structure of rod I used a Delrin rod. Now Delrin is very common name but scientifically its named as Polyoxymethylene (POM) or even Poly-formaldehyde. It has a high strength, hardness and rigidity which make this material very suitable for this job. This material can be sourced from any local plastics supplier. I got myself a 2 ft rod with 2'' diameter.
Tools Needed:
- Lathe
- Drill press
- Drill Bits (Long enough so that hole you can push it right through the length of rod)
- Files (For polishing out)
- Hack-saw
Now, before you start working make sure you have the basic wood working tools and some hands on experience with them. Foremost you must have a lathe and a drill press! Without these machines this job is nearly impossible.
Initially, I tried making one with a hand held drill machine and a bench vice, but the level of effort was very high and within minutes I was tired like hell! So took this job on a lathe and found out it to be more efficient.
Step 1: For my requirement, I needed my frame slider to be of minimum 6 inch in length. This length would make sure my rod is long enough that the mirrors won't kiss the ground if ever the bike falls. So using the hack-saw cut 2 rods for either sides.
Step 2: Installing the rod on lathe and ensuring the stock is 100% centered.
Step 3: Crafting out the rod as per your mounting preference and clearances on the bike. Over here I used a chisel to flat out the cut surface of the rod. Also used the same chisel to craft out the rod along its length. Rounded of the edges to give it a more of a professional and decent look. See the below image for more understanding.
Flattening out the cut surface.
Rounding of the edges
Ultimately after spending few hours I could make 1 of the frame slider. Repeated the same process on the other side frame slider.
Post this process I used a 20x10mm solid aluminium bar. The reason behind using this bar is because of its strength over the SS fabricated plates. Also it was easy for me to use aluminium plate as it a matter of only 2 holes: 1 for mounting on the bike frame, and the other for fastening of the frame slider on the bar. Sorry I did not take any pics during this process.
After making the plates mounted them on the engine mounting frame points near radiator. Did the same on the other side. See the below image where I mounted the bracket. I have circled the mounting point.
Ensured, clearances are enough between the bracket and engine and even if it bends will never hit the engine. Mounted the fairing for some extra measurement and after ensuring everything is aligned properly screwed up the frame sliders. While making these sliders I slightly miss calculated on the length of the rod and ended up getting only 4 inch of rod outside the fairing surface. But even after having only 4 inch of rod outside the fairing surface, these sliders are still way too much longer than those present in the market. For the time being these will do their job, later on when I again find time will make new ones of perfect length. (Touch-wood. They should never get tested
