Sorry about my previous post - turned out to be something quite different than the shock-bolt washer. Here's what I think happened, for any who read this crappy thread :) - upon removal this morning, a small chunk of bolt thread chipped off and damaged the innermost thread (aluminum curl and...

Alta MXR WP shock (stamped -01) w/Race Tech SMGV 5003 Gold Valve piston kit & SPNV 0512 nitrogen charging screw, Zeta ZE56-32250 10mm lowering spacer, and custom-machined graphite-impregnated nylon check valve / spring for Dual Compression Control (replaces DCC shim stack). 50+ Race Tech kit...

When I first started riding electric in the summer of 2014, I was a little disappointed at how heavy the front end felt as compared to my ICE dirt bikes. I tried a number of things and kept the ones that worked, ending up with a bike that popped the front up easily under 25mph even when...

My MXR now has 18 x 2.50 and 21 x 1.85 Warp 9 rims, with a 19 x 2.50 wheel waiting on a tire. I've had 3 rides on the bike after the swap (new tires too, NOS Dunlop MX-31 120/90-18 and Bridgestone M59 80/100-21). Conditions were hardpack / rooty - rocky trails / loam / sandy loose dirt, most...

Just a heads-up - both my front brake caliper's right-angle cotter pins (Brembo p/n 5454232) were gone, and the pad-retaining pin was barely hanging on with @ 2mm engagement. :( The first time I removed these things I didn't like how easy they came off, I'll use straight bend-type cotter pins...

Just got back - a smallish show, but some cool stuff nonetheless. There was lots of interest in Zero test rides (small indoor track), and a Zero's set up on the wheelie machine too. I saw a Heidenau K74 rear tire (intermediate, 140/80-18's > 6" wide) which looked like it might hook up well...

From the MX firmware page (all models have a similar entry): MX_1.5.1 (7/25/18) - support for additional 65-degree throttles Does anyone have any nuts-and-bolts info on this? Throttle curve and regen are the only user-unserviceable things I need fixed on my MXR, I'm hoping I can address at...

I've had my seat off several times for plastic work, and each time I noticed this large motor/pump looking component directly under the front seat area, where it begins to angle up. This thing is shown in the manual's page 79 (to the right of the meter) and page 80 (RH side of LH photo), but I...

This was kind of a tradition at the EMF forum, and since Alta really values owner input it's like one-stop-shopping for them. I did 2 years since the EXR's already in the pipe. My list: Model-specific owner's & parts manuals (online is fine) Modular hot-swap batteries, like the Zero FX (mine...

Not sure if this should be posted here, but anyway... I just finished changing out most of my MXR's plastic with plain white. I used a Cycra front fender I got at HVM (I'd use Acerbis 2141810002 instead), Acerbis 2401265413 fork guards, and the rest is Alta OEM stuff. In the past I've replaced...

Does anyone know if aftermarket fork guards are available for the MXR AER forks? The only bike I know for sure uses this fork is the '18 KTM Factory Edition 450 (KTM p/n 77701094100EBE for the pair) which doesn't seem to have much aftermarket support yet. Ray

I just checked my MXR's coolant level after reading Oded's recent overheating post, and as far as I can tell my bike is bone-dry (no coolant 6" down fill pipe). According to the manual coolant filling takes about an hour, so maybe with the new bikes/prices the assembly line got busy and this...

Just finished assembling & installing the Alta MX kickstand (p/n 8203563-00, $130) on my MXR. It was a very different experience than the Pro Moto Billet unit on my '08 YZ250F (unbolt LH peg, install kickstand, replace peg). I was amazed to find bags of parts, an arm without a foot, etc...

Great forum! Thanks much to Oded for the heads-up about it. I just got my MX-R last week, from Hudson Valley MC in Ossining, NY. They're a very helpful and can-do dealership; based on my experiences so far, I'd recommend them highly. I haven't taken the bike out yet, but I test-rode a '17 MX...
