    Riding style/gearing?

    I think we only had one or two guys in Europe who were hardcore supermoto guys. In motocross we do gear it down often in order to tame down the jerky throttle, use a more aggressive map, and have more power at higher speeds. The feedback from Alta is that for hardcore supermoto an MXR would...

    Did you buy that LHRB kit from Stark, or did you just buy a Brembo clutch master cylinder?

    Owner's Review Stark Varg - First Customer Review!

    If someone doesn't beat me to it, I will post that chart soon after I get my Varg. I will take it to the same DynoJet 200 where I tested my Alta MX and MXR. I have no doubt that it will post about 80hp, and it will be a plateau and not be an instantaneous low-PRM spike. Else, the bike will be...

    Owner's Review Stark Varg - First Customer Review!

    You looked scary fast by the end of Day 2. You were carrying a lot of momentum and accelerated hard only for a few seconds. That was impressive. Then you cranked up the power to 80hp and the natural flow ended. Those pesky corners started coming at you too fast and unexpectedly too soon!

    Owner's Review Stark Varg - First Customer Review!

    Wow, they are selling the rear caliper for that hand brake too?!! Did anyone notice if the Stark used the Formula Brakes rear caliper with the LHRB setup? Or do they use a single-piston Brembo (bleh...)?

    Owner's Review Stark Varg - First Customer Review!

    The piston size alone is irrelevant without the leverage and the piston travel information. A 9mm on a Brembo may not be the same as 9mm on a Formula Brakes, unless the leverage and the travel are exactly the same. You can always install the Alta LHRB...

    Owner's Review Stark Varg - First Customer Review!

    The Alta LHRB uses a stock KTM/Brembo clutch master, and it works fine. But in Bryan's video, the Varg is using a bigger LHRB master cylinder reservoir. It is just as big as the front brake master cylinder reservoir. I have only seen such big clutch reservoirs on pros' bikes.

    Alta MX Cone Valve / Trax Suspension Swap

    You went with a heavier rear 66N spring than what I had, so you definitely should go with at least 5.4N/mm (0.55kg/mm) front springs. You are in an uncharted territory with these dampers and springs. I know people have run them before on Alta's, but you are using a different tuner, so this is...

    Cake Bukk - new high end dirt bike

    This looks pretty good. Replace that front fender and it will look like a mini-Alta. What are the wheel sizes? I couldn't see any specs on their site.

    BREAKING NEWS: Amprius Creates a 500Wh/kg Battery

    The math shows that the Alta/Stark battery would become either 35 - 40 lbs lighter, or will have more than twice the capacity. This is huge. But as skeptics in the YouTube comments point out, battery tech breakthrough announcements happen fairly regularly, but we haven't seen them in...

    Tesla Powerwall

    UPDATE 2023-03-13: Apparently, Tesla Powerwall is now available for purchase without having to buy solar installation with it. $9,200 each. Additional units are just $8K each. And they already have a 5 kW 110/220V split phase inverter in it! There is also a 30% Federal tax credit for it, so...

    Alta MX Cone Valve / Trax Suspension Swap

    6.3 kg = 62 N. The conversion factor is 9.81. 6.6 kg = 65 N. You need a 65-260 spring with the WP internal diameters. I dug up my email records and this is what I bought from Slavens Racing (back in 2018, when they had these springs): Product Quantity Price Fork Springs WP48mm 44mm x...
