Hello, unfortunately i just sold the last spacer I had left about 3 weeks ago. I don’t have the data as a file though. I had 10 pcs. made but they are all gone now. It’s the shape of the aluminium gasket though. So if you have such a gasket just make ... more »

Do you know ANYONE putting more stress on a wheelset than the factory guys? Obviously those guys doing what they do put super stress on their equipment. They are pounding their equipment day in & day out too. But 99% of MXers don't even get close to such abuse yet people go out and buy fancy coloured wheels.

I can only repeat: DON'T get a PC !!!!!!!! I did so myself and after just 3 laps i took it off thinking i must have had a engine failure. It was that bad, really! Ever since it is hanging in the corner alongside some other exhausts i tried...worst investment!

On such bikes you need to do a full disassembly to inspect and rebuilt basically everything! I have rebuilt 3 such bikes from scratch. One was my '89 VRP full aluminium custom bike. You can check my builds in my Flickr-Albums here Nino's '89 VRP: https://www.flickr.com/photos/ottospeed/albums/72157657243148579

Weight on wheels is the most overlooked area! A typical Talon wheelset weighs 2,5 kilos (!!) more than a stock Honda wheelset!!!! Wheels must be accelerated to get them spinning...heavier wheels need more energy to get up to speed ---> you actually LOOSE POWER with heavy wheels!! There is absolutely no benefit of running a CNC'd hub. Or have you ever seen a broken cast hub??? They do CNC as the mold for doing cast hubs would be much too costly. CNC is cheaper Spokes: again - why would the OEMs offer expensive double butted spokes when they could put cheap straight-gauge spokes instead?? Did you ever ask yourself? Cheap straight gauge spokes are cheap and much heavier and much less unforgiving. You are more likely to break a straight gauge spoke than a double-butted spoke. The flex the double-butted spokes offer is needed to absorb peak stress! Stock rims are indeed softer but again-they are also lighter and i can only insist you guys keep rotating mass as light as possible. A typical set of aftermarket wheels weighs just so much more. Let's talk about suspension for a second: more unsprung weight....that's making for less sensitive suspensions as each, the forks and rear shock, have to move over 1 kilo/ 3 lbs more up & down...a heavier wheel can't follow the ground as good as a light one. It's as easy as that. You see guys concerning more about color options than about performance....for me an absolute waste of money and one of the biggest downgrades on your bike!

You missed to mention that the engine is developed by MUGEN which are pretty much leaders of E-Motorcycles. Just look at their "Shinden" bike taking victories at the TT of Isle of Man....there are tests of that Shinden Racebike.

Yes - i tried the '87 on saturday (the video is from Sunday). The 87 too mounts a Mugen kit and some trick parts....however the real owner (not the guy i'm following in the video) isn't going that fast so he runs it with a 36mm carburetor which definitely

This cylinder has already been sleeved. I personally would get a new cylinder with Nicasil plating right away. Get a quality piston like Vertex or Wössner at 0,05mm of play and off you go. On HPP engines one good upgrade is to get the HPP valves &
