Must say, it's a brave thing for Triumph to do. I'm genuinely surprised, but it'll be good to have another manufacturer in the marketplace. KTM get away with a lack of competition right now.

I wonder if Triumph will do a 2-stroke? As an engine type it has no future, emissions-wise, and at the very least it would have to be TPI - which isn't an easy thing to pull off. Easier for MX competition-only use, but for road-legal leisure enduro riders it's pretty difficult to produce a bike in a volume that requires full homologation. KTM really struggled with the EXC300/250 TPI and they've been making 2Ts for decades.

Personally, if Triumph made an electric enduro bike weighing under 115kgs with true 120km range and about 20KWH, I'd be a buyer.

But I imagine they will go the 4-stroke 250/350/450 route. Hopefully they'll make a proper dual-sport too. They should call it the Triumph TETaTET.

If it was to happen at all I think it would ultimately be aimed at the emerging markets of Asia and probably only to foster brand loyalty for it's bigger bikes. So a carefully selected manufacturer (in Asia) worthy of the Triumph badge fitted on a small dual sport bike to keep them flying out the door as per Ktm and BMW. No need to reinvent the wheel.
Open your eyes and you see what is in front of you, open your mind and you see a bigger picture but open your heart and you see a whole new World.

The Honda CRM 250 AR was a two-stroke with very low emissions. Active Radical combustion used very volatile single oxygen molecules (free radicals) to clean the combustion process with an exhaust trap valve to ensure that it happened.
You can quite easily get a two-stroke to meet Euro V in terms of NOx....some people have got old-school strokers through the London ULEZ test. Particulates and unburned hydrocarbons are a problem...but an AR direct injection two-stroke could address both. Two-stroke direct injection has already happened with snowmobiles and outboards which have to operate in sensitive natural environments: only inject the fuel once the transfer ports have closed and before the exhaust port opens.
A few years back I had an interesting conversation with the designer of diesel injectors at Delphi (now BorgWarner).
They were very proud of a diesel injector that used electronic control to produce several pulses of fuel during a single combustion 'event'.
"Could you use this technology to power a high-revving two-stroke?" I asked.
"Funny you should say that..." he replied.
