    X Games Bans Electric Motocross Bikes In Bid To Become Even Less Relevant

    Here is an attempt to go back to 450s. The conclusion is that in his opinion the Stark is more exciting, more performant and safer for jumping. I am a slow motocross rider and I agree.

    questions about 96v 450

    Some 450s have specific supermoto frames, for example TMs and old Italian Husqvarnas. TMs have been pretty successful in recent years in supermoto racing and usually those riders who use CRFs etc. for supermoto prefer the TMs when they try them. Probably the engine played a role in the...

    Might want to check your CAN bus connection

    Wow, I read in your signature that you used to work for Alta! Sorry if I didn't include you in the list of professionals who could answer that reliably; probably there are other users who are professionals too that I'm not aware about. Of course if someone who is not a professional has...

    Might want to check your CAN bus connection

    There is still not much information available about the internals of those batteies, so first of all don't tinker with them because you risk ending up electrocuted! Keep calm because worst case scenario it's better to lose 3K $, buy a new battery and maybe even end up hating EVs, selling the...

    Might want to check your CAN bus connection

    One solution could be to clean with contact cleaner or the purest isopropyl alcohol you can find, dry and add dielectric grease, provided Stark approves it. You should be careful, though: listen to what this girl says about sealed connectors because I think that's wise advice: Now, surely our...

    The FASTEST Car You CAN BUY! McMurtry Speirling Pure BREAKS RECORDS

    Enjoy! 🍿 You can also, somehow, try one yourself! I think I'll download it, I use Assetto Corsa sometimes! Just apparently according to the comments the suction is not really simulated: it just behaves like it had very sticky tyres. May look for another one, then.

    Supermoto on stock Stark Varg MX

    Did the bike show any tendency to slide because of the engine braking? I guess not, for these reasons: • It seems to me that, even when set at 100%, the engine braking of the Varg is not so much. • Something that should be kept in mind when using some kind of BigFoot setup is that the braking...

    Supermoto on stock Stark Varg MX

    Your setup reminds me of the Supemoto BigFoots that Gianni Borgiotti, an Italian supermoto rider, who used to be (still is?) almost pro level and still is an instructor, tried to spread years ago; he also competed in the S2 class (for the fastest amateurs and slower professionals) of the Italian...

    Owner's Review The Torpedo bat of Dirt Bikes, first impressions.

    That holds good for me, too. If my heart rate monitor still worked or if I had a smartwatch I'd like to check my heart rate on the Varg and compare it to what I got on ICE bikes.

    Owner's Review The Torpedo bat of Dirt Bikes, first impressions.

    In my tool kit there are two torque wrenches and one of them can do from 2 Nm to 26 if I recall correctly.

    Bonnell 40hp and 60hp dirt bikes and e-bikes

    The main reason for which a more conventional fork diameter like 48 mm would sound better to me is that I think that with 43 mm there would be too much flex and therefore too much binding when the inner tube slides inside the outer tube. And, like you can read here, even at Luxon they think that...

    Bonnell 40hp and 60hp dirt bikes and e-bikes

    Josh Hill uses them with Surrons and does amazing things with them. Keep in mind that he does amazing things with the stock suspensions, too, though. The only electric dirtbikes I've ever ridden are Vargs and Talaria Stings. The suspensions in the Stings felt aweful to me; I don't know whether...

    Bonnell 40hp and 60hp dirt bikes and e-bikes

    I won't comment about the bicycle, only the motorcycles. Things I like: • A controller which is made with EBMX, so maybe it can be bought separately, even if Bonnell can't provide it anymore, and hopefully still work. • A motor that also looks like one of those that can be bought for...

    Interest poll: What kind of charger would get your money on the table?

    I agree about the fact that there should be an onboard charger for the EX. For the MX, A. Wass said that the battery could safely be charged at at least twice the speed, so let's say 7 kw. I would be interested in some kind of fast charger but only provided it can be used at the track: as of...

    Stark Inverter Question

    Hey guys, I've found out some tech talks in the Lucid Motors' YouTube channel which are pretty awesome! Here is one in which they explain how their inverter works. It controls a permanent magnets motors which is roughly similar to the one of the Varg and probably a lot of what they say in this...

    Stark Varg inverter cover removal

    Typically, in inverter assemblies of EVs, there are DC capacitors, used in the pre charge circuit. They won't discharge immediately after having been disconnected from the battery and they can kill someone who touches them if they are still charged enough.

    AMA and Electric Motorcycles in AMA races

    I'm not an expert but I have learnt something about those batteries and I doubt that they could have available anything so different from what we have. Just check the specifications of the battery of the Ducati V21L used in MotoE, where probably they are willing to spend more money: the energy...

    Now that I think about it, I've seen it on circlip mounts as well; probably you are right.

    stark varg ex supermotard

    I never buy aftermarket front sprockets because I fear that they may damage the countershaft because of some characteristic of the splines. For example, the splines may be too hard or have an excessive shape error or the wrong play.

    Stark Varg: Gearing for optimal range

    I like the idea of considering in which rpm range the motor is the most efficient, but I think that the AI has confused things here, since as far as I know the Varg motor is a purely permanent magnets motor, while the permanent magnets reluctance motor is a special hybrid solution used in...
