    Formula master cylinder rebuilt kit? Or Brembo rear master cylinder model number?

    Since there shouldn't be any official rebuild kits for Brembo, the ones you can find online always made me suspicious about them. Therefore, years ago I turned to a local company specialized in rebuilding brakes for my supermoto. I sent them the master cylinder and the caliper and they cleaned...

    Stark throttle/hand grip

    Personally, I struggle in general to keep my elbows high and I fell discomfort when I need to twist my wrist much. I can't customize maps yet on my MX 1.0 and one of the reasons I keep power settings probably higher than what I need is that by doing so I will get the power I want limiting the...

    CR-E “250” Project

    I like the idea of using both simuiltaneously because: • splitting the cells into more than a battery increases the overall surface and as a consequence the cooling capability • splitting the cells into more than a battery makes it easier to use as much space as possible in a motorcycle that was...

    Electric Clutch Reviews?

    So let me recap: • radial master cylinder for the rear brake: please contribute here • dual caliper rear brake: please contribute here • oversized front brake rotor • super cool shiny chrome/violet/carbon fiber look with stuntpegs • now you also have e-clutch, throttle response adjustment...

    Does “storage charging” work for anyone?

    In my manual for my MX 1.0, revision 8, they say 30-50%. I second the idea that the SoC may be too high to enable a storage mode.

    General WTB Chick bike

    You may find this thread useful. What will she use the bike for? Trail riding? One problem that I've had riding small bikes is that the seat was usually too low and so when standing my knees were not squeezing anything, because they were above the seat. I suggest that she checks whether she can...

    Home built linkage guard skid plate

    A2-50 apparently is what I know as AISI 304. I like the steel choice: stainless and with little tensile strength, it's roughly the same strength of a 5.6 screw. Honestly replacing the OEM screws sounds a little risky to me but especially if they are not too sturdy and break instead of damaging...

    Home built linkage guard skid plate

    Thank you but I can't accept this compliment because I don't have a degree. After all, E. Musk said multiple times that you don't need it in his opinion and that you can learn everything for free nowadays. Surely there are reliable sources of information online nowadays and also my experience in...

    Home built linkage guard skid plate

    Some considerations: • One of the problems of a short thread engagement is the possibility of loosening and IMO the thread locker would solve that. • Bottoming the screw out against the OEM screw underneath will affect its clamping force and I think it should be avoided. • Generally, the idea of...

    Stark Varg SM order status & delivery times

    I know this topic is not for compliments but with that light, the red plastics, the matching red center stand and those beautiul detalis it reminds me of Ferrari cars from the eighties. It would look way better than a painting exposed in a living room, lit by a warm light.

    Owner's Review 2017 Alta Redshift MX factory demo at Hollister Hills SVRA

    Hey wait a second. In this video, at 2:28 AJ says that Philip has some high bars and that bike has Alta Owners Forum stickers. @Philip: is that your Alta?

    Home built linkage guard skid plate

    Remember that Stark has stated that using an aftermarket skid plate would void the warranty; I don't know about a modification like this one. You could try countersunk screws to avoid having protruding heads.

    Service your linkage and swingarm bearings asap

    @happyinmotion: thank you for having shared your experience. I dislike this design, too. My Husqvarna SM 610 has grease zerks in the linkages and I love them. I wish all bikes had them. Maybe for enduro they may risk getting damaged but for motocross and supermoto it shouldn't be a problem...

    Stark Battery Tech Thread

    I think that one of the main technical problems is heat. Let's say that a fast rider uses the whole charge of a 6.5 or 7.2 kWh battery in 0.5 hours, that means that the average power output has been roughly 14 kW. On the straightaways he probably used way more but then there is also braking and...

    Service your linkage and swingarm bearings asap

    I'd also like to write some suggestions for when reinstalling the rocker arm, since Stark's video procedure is to just loosen the reverse thread locknut and then apply 5 Nm when reinstalling it: this may work for a clean bike but maybe not with a dirty one, since the reverse thread looks like an...

    Service your linkage and swingarm bearings asap

    I remember trying to remove the crankcase bearings of my YZ250 by pushing them with pieces of wood or other objects hit by a hammer. I remember that at a certain point I stopped hitting them because I was afraid to break something. Then I heated up the crankcases and some bearings fell under...

    Service your linkage and swingarm bearings asap

    Can you please keep us posted on what you will actually see after having removed the bearings? I don't know whether you are servicing an MX 1.0, a 1.2 or an EX but in either case, the picture of the rocker arm that I see on the official site in the spare parts section shows three bores without...

    Talaria Komodo

    I'm not so sure about that and I don't understand why they make those bikes sturdier. We have two problems: • strength: I think that strength is given mainly by the tensile strength and by a low enough density that allows the manufacturer to use more volume of metal keeping the weight within...
