How To Build An Electric Motorcycle. Get the plans: https://renewablesystemstechnology.com/electric-streetfighter.html
In this video I build the chassis for a new electric streetfighter motorcycle. As some of you know, I've been planning and working on the design for most of the year. I took inspiration for some of the cosmetic elements from a few other bikes like the Magpul Ronin (a Beull 1125) and the KTM Duke, as well as my previous motorbike project.

The chassis is all steel. Yes, I know. Again. My flux core MIG limits me to working with steel because no one makes flux core aluminum MIG wire - some people sell it on Ebay and Amazon, but it's actually solid wire that requires gas. I do plan to upgrade to a more powerful arc welder in the near future so that I can use aluminum for projects like this. But for now the extra 15-20 lbs isn't going to make much of a difference, especially since this bikes total weight will still be 100 lbs less than a conventional bike in its class.

As you can guess from the title, I'll be uploading a series of videos for the build as it progresses, this being the first with two more to follow in an effort to establish a more regular uploading schedule for you folks. This week I'll be making the foam plug and sock and mother molds, then use them to cast the fairing components. Keep an eye out for that video in the next week or two. The final video will be the complete build from start to finish, with a short test drive at the end. As always, a complete set of plans with a material list will be available when the build is finished. Links for suppliers of the components featured in this video are below.
