Motorcycle manufacturers have difficulty getting 4 cylinder engines through Euro 5, which is why the switch to 2 cylinder motors. I applaud them bringing out retro styled bikes using these modern liquid cooled parallel twins but they're just not the same when what they're trying to imitate had an in-line 4.

I do not buy this statement at all..... they can deliver them and meet Euro 5. The technology is available and ready.
The problem is: are the customers willing to pay for it?

What might be that technology [url=http://cb1100forum.com/forum/member.php?action=profile&uid=3454]PB ?

My general understanding is they would likely have to suffocate the 1140 cc inline-4 even more, thus a likely loss in power somewhere, and/or add a much larger catalytic converter lunchbox which will increase purchase cost.

Many larger twins have been using dual sparkplugs per cylinder for over a decade now. The inline-4s don't have the luxurious real estate for that.

If demand is there, they'd probably do one or both. Is there a better way that won't significantly increase cost? Adding water-cooling will add cost to the CB1100.

Take for example the Moto Guzzi V85TT: Have you seen the underside catalytic converter? It hangs kinda low like an alien sac.
