I think Audi have done it before Honda. It needed a 48v battery and was used to spin things up before the turbos took over.

I guess li-ion batteries mean it can be reasonably light but it's still 2 batteries required to run the bike

'leccy compressors have been a thing for ages. As above, in various Audis. They're in loads of industrial applications too and shades of the same thing in F1 and Le Mans.

Honda are just claiming the first bike?

I doubt it'll be cheap

I don't know who was first to use a compressor & I think it's a different use for it but they've been using compressors in Moto GP for years for the pneumatic valves.

Yeah that's a much smaller compressor. You need to be compressing litres and litres of air to boost an engine, not the few CCs a valve system uses. Think about it, a 1 litre 4 stroke consumes about a lire of air every two revolutions, so it needs about 5000 litre/min of air. to run at 10,000rpm* All that has to go through the compressor before you even start adding the 'extra' stuff for boost!

MotoGP don't even necessarily need a compressor for the valves, sometimes they can just run with a tank of compressed nitrogen. We used to make the carbon wrapped pressure vessels for some of the teams. Just pumped up really naffing high (>300 bar) right under the rider's nads.

EDIT: LOL, it says that in the article Well, it doesn't say I used to make them

*incidentally, this is why the induction system is so loud

I do like that 650 Classic, shame the engine isn't very characterful (imho).
