I realized that not many people have read my long Re-springing a 2017 Alta Redshift MX (and then revalving too) thread. In case you missed it, Alta's factory MX team has developed updated suspension specs for the MX model. They shared it with me, and they said it was okay to share it with other...

If anyone wants these factory developed MX suspension specs, send a PM to me with your email address.

Only torque (at the rear wheel, to be technically correct) changes with different gearing. The HP does not change with gearing. Power = Torque * Speed. The torque goes down, the speed goes up, the HP stays the same. What changes is the speed where that max HP occurs.

Yes, we definitely need a bigger map indicator on the display. I can't really slow down and lean in during the race to read it. That one digit is too small. It should be at least as big as the speedometer. BIGGER than the speedometer on the MX and MXR models, who needs a speedometer on these anyway.

:ROFLMAO::ROFLMAO::ROFLMAO: I laughed so hard when I read this!

Whoever wants the Redshift MX factory recommended shim stack specs for the 4CS fork and the MX shock, please PM me your email address where you want these sent. Thanks.

In motocross, at my local tracks, I never exceed 45mph. So...with a 14-tooth front sprocket... In Map 4, I would get the acceleration of the stock Map 3 at low speeds and the acceleration of the stock Map 4 at high speeds. In Map 3, I would get the acceleration of the stock Map 2 at low...

Well... I was too impatient to wait for the dyno data, so I digitized the MXR Dyno pictures. I wanted to see what a 14-tooth front sprocket would do to these curves. Here you go: ____ Power MXR Map 4 ____ Power MXR Map 3 ____ Power MXR Map 2 ____ Power MXR Map 1 - - - Power MXR Map 4...

Does the @MotoMinded light kit comes with a horn? I saw the horn button! Can we specify an air horn when ordering? :p

Doesn't Magura use mineral oil instead of brake fluid?

I think this number "09" indicates the diameter. This is @snydes Alta kit.

Where is the supercross track, Butch?!

I too would be interested to know if Alta uses the stock Brembo clutch lever. But regardless, I am now tempted to reproduce what Mark911 has done -- install a bigger slave cylinder.

Kreft Moto makes awesome stuff. Their products new and original, they do their own development both at the track and on a dyno. They do not have their own shim stack specs for the MX yet, and are unlikely to have them soon. They can put in the factory recommended shim stack specs though...

The Rekluse LHRB is all hydraulic. It pressurizes the stock rear master cylinder from the top. You remove the stock rear master cylinder cap, carefully place an O-ring in there, then screw in this black insert. Then attach a hydraulic line to the top of it. The mechanical one the the cable...

Why not? I routinely cover 20 miles (32km) at a motocross track and 40 miles (64km) off-road. Alta could squeeze out a few more miles out of the battery If they really want to. I think it would last the 35km of the Rodeo, if the wheelspin is kept to a minimum.

Also, another conclusion is that if you are not going to ride your MXR in Map 4, then you could save a lot of money by buying my slightly used MX. ;)

Sounds like Alta is really serious this time about finishing the race, and perhaps even showing a good result... or maybe even winning. They obviously do not want to raise the expectations too high, but such statements are telling me that they are definitely not joking around.

From Alta Motors, today: Alta Factory Racing team riders, Ty Tremaine and Lyndon Poskitt, will make history as they pilot the first electric motorcycles ever to compete for the podium at the Erzberg Rodeo, the most challenging off-road event in the world. Part of the Red Bull Hard Enduro...
