There are many snow bike conversion kits. I can't compare as I'm using just the Explorer which I bought 6 years ago. It was together with the wheels which are very helpful pushing the bike into the garage. You can use the KTM 350 kit. You just have to make 2 new spacer rings as those don't fit...

I think spring of next year. I suppose that the sales will start in Europe first. Individual purchases from US might be possible similar like we had bought Altas in US 4 years ago and organized the transport to Europe by ourselves.

The FIM e-Dirt Bike Meeting took place in Saint Chamond in France on 2nd July. About 60 people from FIM headquarters, country FIM authorities (mainly Europe) and some e-dirt bike producers took part in. The FIM representation was quite strong – Antonio Alia Portela – Director Motocross...

You are right. It may have an old-school look. But – the same progressive damping performance like state of the art monoshock with linkage, 1+ kg lighter assembly, better center of gravity and 25 % more space for the battery. What do you think, does the “old fashioned” look pay off?

MXM - Inspired by ALTA – by her beauty, high performance and joy of ride. Designed by its own way after ALTA's production had been discontinued. Photos from the FIM e-Dirt Bike Round-Table and Testing in Saint Chamond France last weekend.

It would be an honour to present the opinion of the members of the Alta forum. The question is how many of us do agree to what you wrote above. I do absolutely. We are definitely not 924. I would guess 400? I don't know but we are for sure the most numerous group of users of electric dirt bikes...

I'm going to be there. I'll let you know.

Hi guys, it looks like FIM wants to accelerate the expansion of e-dirt bikes and e-dirt bike races. Jean-Paul Gombeaud - the FIM Sports Direktor - is organizing a Roundtable discussion and testing on e-Offroad motorcycles in France on 2nd July - see attached letter. In addition to this meeting...

Thank you. Fully agree with respect to the development which followed after Mono-Shock and Pro-Link market introduction in later 70th. According to what I read the original reason was to get space inside the frame for the exhaust pipe.

Does somebody know what has been the main real technical reason for using single shock instead of dual ones since Yamaha developed its Mono-Shock system in 1972 on MX bikes?

Hi, I imported an Alta to Europe in 2017 and another one last year. Both by air. The transport in 2017 was fast (2 weeks), for a good price (1.100 USD) and no problem. Very contrary of the transport last year. The reason was that the rules for transport of lithium batteries have changed and...

This is the Chinese origin.

What do you think about this one - just 64 lb and works well with rapid 230 V charger. I have been using it to charge my both Altas for 2 years. You can easily load it into your truck by one hand.

Unfortunately, ultracapacitors haven't been so far develped so that they could replace batteries in electric vehicles. Their gravimetric density is about 20 times lower than at li-on batteries (10 Wh/kg vs. 250 Wh/kg) and the price for 1 kWh is about in the same ratio :rolleyes: Their only...

She probably hasn't seen anybody riding and Alta :muutt:She might be surprised :p:ROFLMAO:
