Yamaha SR250 - A clean standard build

The left side cover has been a bit of a nightmare. Turns out it's pretty far away from being a straight mirror part. I had to remodel it from scratch rather than mirroring the right side and tweaking it. The frame is slightly different and this side needs to cover the air box, which sticks out quite a way - in comparison to the relatively flat and flush battery on the other side. I'm onto the 2nd prototype already, hoping this one (on print now) will match up better and clear the bottom of the air box!

Right, I'm on to the 3rd and 4th prototypes of each of these covers and still fluffing around with the fitment and the detail.

In the mean time, I am contemplating what sticker to place on the covers. I'll probably get them vinyl cut in either silver or mirror vinyl. I really like the old SR500 logo - came in a couple of variations, so I have tried that. Then the logo on the tank of the late model SR250's is also actually pretty cool - a bit more modern graphically. Could work, just not sure it fits. Then of coarse I am toying with the idea of putting Jadus on the side - this would be good to get the name out there but I am not a fan of blatant promotion. Not so smart business wise maybe but for me its all about the design. Not ruling it out, just cautious of it is all. I could use just the text, or just the logo, not both. Thoughts?

Firstly, this is a badass awesome thread :D

Addition of kickstarter or kick conversion ? Some time back I had to round up used XT250 parts to convert.

I like the last logo the best over the text, but I think all of them could be smaller in relation to the Yamaha logo

Of those pictured, I like the last/logo better than the script.
+1

The Jadus logo looks good and in my opinion isn't "in your face"....

Thanks! I've been watching your vids for a while now and love your sense of humour ;D

I actually have all the parts for a kick start conversion, but decided it wasn't right for this build. I'm saving it for the next SR which is going to be more racer focused. More on that later/when this one is done!

Well thats a good few people in for the Jadus logo, awesome. I'll play a bit with the size of it and it's position.

Just signed a contract and started a full time job again, so I am glad I am real close with the build :)

Signed up with the man eh... Don't loose sight of the dream mang!
:eek:
Haha, yeah, back to the grind, back to the hamster wheel if you will :-\ The dream is still very much in focus though! This is just a means to an end and hopefully, not too long term :)

Closer and closer with these damn covers. Made up a few prototypes now! You can see in the last pic the curves I have been tweaking a bit at a time to get them to match the frame.

I am also considering if/how these could be produced in scale. Injection moulding is obviously the preferred method and is how the originals are made. But the tooling costs would be astronomical - based on the fact they are quite large parts and would require slides in the tool. Sure, there are ways to simplify the design but then the covers would need to be an assembly, rather than a single part. It is also really difficult to gauge if there would be enough interest to justify such an investment! I'll mull it over for a good few months at least.

a fiberglass/carbon fiber composite would probably be the cheapest to tool for a small run of parts. but maybe not cheap enough to be at the price point you want.

Might depend on how you intended to fasten them from the back. Maybe 3D printed units (on demand) to fasten/glue over existing tapered panels so no difficult fastening methods needed.

How about using thermo-forming over a template? You could even make the transparent if you'd like to. If you get the mold right it would be really cheap and fast. However you would still have to mount the fasteners afterwards.

That gap won't pass the hotrod filler spreader test but looks dang good to me ;D
Haha, yeah, I have made a new version since this one, was not satisfied with that gap, or at least, the inconsistency :-\

All good input thanks. Yeah, I am now investigating composite manufacture. Cheaper tooling and shorter production runs. I'll just have to figure out a way to attach the fixing points easily, perhaps they can be 3D printed like zap suggests and then epoxied in place with a jig. Food for thought for the holiday season!
