For all motor biking travellers out there.
Ever gone on a long ride and felt that cramp in your hand which is a result of holding the throttle down?
I did, particularly in the last ride where I rode continuously for Nine hours straight.
So I came about looking for some options and as usual couldn't find any viable options. The ones I did find, I realised the cost of most of them was equivalent to my kidney.
NOTE: This is only a prototype. Although i have tested it out, I however have not tested it on extreme weather. SO do ride with caution.
Step 1: Acquiring Materials
When I realised I need to build my own, I came across gathering the next of materials that I can fabricate things with at home itself.
So the Items needed were:
- PVC sheets; I used credit cards because I had a lot of expired ones at home
- Screw and bolts x 3 ; I picked up a screw with a 6mm head and half an inch long. The girth of the screw doesnt matter here as much as the length of it.
- Spring; I pulled mine out of some old ball point pens and clipped them to size.
- L-bracket; a single bracket of 3/4 inch size.
- Round Clamp; to add traction to the throttle.
The following items are required in general:
- Wire Cutter
- Screw driver
- Adjustable wrench
- Adhesive - Fevi Kwik
NOTE: I made this in a completely organic manner. The length of the screw, the length of the spring and the round clamp are picked from observation of the fittings and size. My throttle has a grip installed on top and required a 1.5" clamp. Since that was unable, I used a 2"clamp and brought it to fit on the size. SO those who are planning to make this, measure the diameter of the throttle for the clamp size.
Step 2: Building the Switch
I cut the cards (PVC) in the size I felt would be suitable ergonomically.
The base had to be 2" long for my usage, but those planning on using it should check the provisions for installing it.
I created a ply out of multiple layers of the credit cards to avoid any chances of shearing and sagging while using it. All the plastic elements, including the lever and the base has been created with this ply. The vertical mounts for the lever have been reinforced with fevi-kwik.
Once fixed, I drilled 3 holes into the module.
- Between the verticals, where the screw (stop screw) passes.
- On the flat face of the Verticals to fix the lever.
- On the end of the base to fix it to the handle bar.
Take the L-bracket and screw it to the hole no. 3.
Fix the lever with a screw as shown to hole no. 2.
Fix the Stop screw to the hole no. 1 as shown. Pass the screw through the spring and fix it with the nut on the other side of the base. Use the nut for adjustment so that the screw does not obstruct the movement of the lever.
Step 3: Mounting the Unit
Tighten the round clamp around the throttle.
Mount the switch to the handle bar. I ride a Royal Enfield so I had the advantage of fixing the switch to the accelerator unit
Step 4: Finishing
Now that you are done, Time to take your motorbike out for a spin and flex that throttle hand of your's while you ride.
