Fuckin hell man!!! I was screaming those last few laps!

What could he possibly have been making an "excuse" for if he won the race? I mean god forbid he tells us how he's actually feeling and gets emotional after all that he's been through, from constant illnesses to constant hate and negativity from people like you. I think he can be EXCUSED for shedding a few tears after that win.

I usually ignore your posts and I will continue to. I just want to say that when I do accidentally read your dribble, you sound like a miserable person and I really hope you make it through whatever you've been going through.

I just checked my memos and if you want the correct shock body(CRF will fit, but adjuster might stay under plastics, not sure about Alta?) get KX450 09-14 shock and that KYB Kit clevis.

If you really want KYB shock, you can source used CRF450 KYB shock 2009-2012 and then order suitable KTM 11-15 clevis from Technical Touch and have your tuner shorten the shock into 490mm. If I remember correctly, 09-12 CRF450 shock is 493mm eye to eye. Top bearing must be replaced also. If you cant find the correct one, order full bearing set for Yamaha and shorten the collars in lathe. Here is the KYB part number for clevis 160350000101 piston rod comp rcu, bottom end KTM KIT '11-'15

Most linkages are a 4 to 1 ratio. So, 10mm shorter would make the back end drop 40mm and that's a lot. Typically tuners can modify shock length for tuning, it's usually 1mm or at most 2mm, chassis balance with these changes can be accommodated by positioning fork tubes in clamps

With regards to battery packs getting too hot, there is technology available today to solve the heat problem. For example, I've incorporated water cooled cold plates and a cooling system into my Alta pack and into a pack I designed and built for my KTM supermini project. However, since typical ambient temperatures are only a handful of degrees lower than the safe operating temps of most Li-Ion cells the only solution on hotter days is to "pre-cool" the pack to sub-ambient (45-50F) temp using a water cooler or "chiller" as shown. This allows much more thermal headroom and you can...

"Competitive" is too vague a term in this instance. Competitive in what respect(s) I'd have to ask? Lets face it, battery technology (at least the tech commercially available today and in the near future at relatively economical cost) simply won't support the kind of range that most off-road racers require. Yes, there could be work-arounds like fast change hot swappable packs, but that would require multiple packs adding thousands of dollars to an already expensive bottom line. So, unless you have money to burn that automatically limits the "competitiveness" to shorter events like motocross. Focusing on motocross only, to be...

I'm a former Alta employee that now works for one of the major OEM's, and I can tell you with certainly there will be a competitive E-motocross bike from many of the major OEM's in the not too distant future. They know its the future and are working on it...

If you are a litte mechanically inclined, XEMX1 has a kit available in the near future for a 2105 generation YZ250F. It is a complete bolt in kit for that gen frame. I have seen a prototype unit and it is very clean. CNC machined cases with gear reduction and motor, programmed controller,battery. Complete kit or parts separately. Perfect fitment and a completely product look. At this point I think they have a website you can look at for video.

This here is why the big 7 won't release a competitive electric motocross bike anytime in the near future. They make a lot of money off parts, and electric dirt bikes will generate far less revenue. I'd be willing to bet that at least one of the big 7 has pretty competitive e-bike waiting in the wings, but that the timing isn't right. Super competitive electric mx bikes aren't just disruptive for dealers, but downstream in engine hop-up companies, pipe sales, clutches, ect as well. Since Alta is no more, I seriously considered a freeride-e but that bike looks pretty...

Sounds like they let him go, he was respectful so that helps, he got the cop to shout out “team fried” JLaw rules. Idc.

Definitely a camera. Doesnt quite look like crayon.

This is the photo from Yamaha gallery for 2021 YZ 125.

Looking at the angle of the silencer/muffler, looks to be a 2 stroke. 4 stroke muffler doesnt look like that. And also it appears to have a cable clutch due to what appears to be a clutch cable tensioner on the left side.

New Yamaha moto being announced 5/18/21. I suspect a 2 stroke,I guess something has been in the works for ahwile.

I'd recommend something like this:
