Just looked at this thread for the first time. Fog 25/Fod, the attached pic looks like LACR. Are you guys SoCal locals? If so, we all should hook up at the track sometime. I'm retired so just about any day is good for me!

Got the initial model done. Need to make a rapid prototype and validate it before spending money on an actual part. Since my mod bracket was fabbed using an oversized rotor this engineering model will be the same. I'll scale another for the stock rotor.

I'll write something up and start a new thread.

I guess I need to restate. I'm not looking for more power, just better "snap" in those situations. That instant rush of thrust just off the pilot jet. Not too much (aka Yam YZ250), but more than I got now. Maybe lower gearing would help, maybe not. But that little 11t is so small I think...

You guys are GOOD!

I added some simple black background on the rear monocoque and other places. I kinda like the "blackout" look. BTW, can anyone see anything special about my WP52mm Cone Valve forks?

Yes, I know that's the conventional wisdom. However, I'm mostly talking about pretty tight typically 1st/2nd gear rut corners where the centrifugal force generates plenty of traction. That's where the ICE bikes can gap me.

I must be the only one who thinks the bike needs more low end pull (all maps). I bought an 11t countershaft sprocket but I'm too afraid to use it, it's soooooo tiny. Going up 1 t on the counter and down 6 on the rear........., that's like 10 teeth total smaller on the rear! Just can't see it...

When Alta first announced it was accepting applications for dealerships I submitted one. There's wasn't much information required so I'm not sure how they screened them but I never heard back. My guess is you need to be an established dealer of some major OEM already. Oh well!

I made mention of this awhile ago as well. They obviously have assembly drawings, BOMs (bills of materials) and at least an entry level MRP system. Between these it's pretty simple to create exploded views with item numbers just like everyone is familiar with now. Those exploded views are...

Wow, Petaluma Ca, one of my old stomping grounds. Used to work at Cycle West in the 70s.

At this time the Vet class IS the only legitimate demographic for most competitions. Let's face it, most "up and coming" kids (anyone under 25 in my book) are going to race ICE bikes that are AMA class legal and give them the best chance for sponsorship. The AMA is really wary about this new...

Chris Keefer was going to include the Alta in his 2018 250F shootout but Alta backed out. Apparently they weren't quite ready with the MXR and didn't feel the 17 was representative. The testing process isn't really suited for the Alta right now. The bike would spend most the day on charger so...

Ok, I'll start the measurement process.

Question is, is it available? I think I got a bunch of "on backorder" results when I was looking. That's why I went to E-bay.

According to my notes the caliper is KTM PN 6001308000130. It's under $200 new without pads (assuming it's still being stocked). There are several other PNs, like 6001308000101 and 6001308000103, the difference is the color I think.

This is awesome! Hopefully, Alta's marketing department will take note and use it. IMO, it's much more influential than seeing videos of professional freeriders and ramp jumpers doing their thing.

If there's enough interest I can create a CAD drawing/IGES file for the dual piston rear brake caliper mount. I can design it to be as basic as possible to make machining as cheap as possible. Most machine shops will take an IGES file and use it to generate machine code for their CNC...

How many of us would feel comfortable populating a typical 20x20 (400 cells) fuel map table for a typical ICE bike? Same for timing and all the various trim tables? With the help of a dyno and the proper instrumentation (exhaust analyzer, knock sensors, etc) one at least has a fighting chance...

It's kinda interesting that the Powerwall is made up of essentially the same cells that power our Altas! Makes sense as Tesla is now manufacturing it's own battery cells at the GigaFactory.
