Being essentially derived from the original Daytona 955, it is technically considered a Street fighter. The Speed triple is not a thoroughbred "cafe-racer" in the traditional sense as it is not derived from a "standard" motorcycle. Traditional cafe-racers are also air cooled as well.
With Cafe'esque body work it would be considered a Cafe-Fighter. A street fighter, with cafe racer styling. In particular, the low bars/clipons, short aerodynamic rounded tail, single fared or non fared headlight, etc.
The Stock Speed triple has Dirt bars, sport bike tail, modern style dual headlights, etc.
My naked 748 has a single triumph 7" headlight, and narrowed Cafe style tail, clipons, etc. As it's derived from a modern sport bike it is still considered to be a fighter though. Hence the Cafe-fighter terminology.
On the opposite end of the spectrum, the Cafe-fighter term has also been applied to older "Standard" style bikes that have been modified with late model sport bike USD forks and rear monoshock suspension.
It's a conglomeration of two separate styles and era's of bike, taking ques from both to create a completely unique style unto itself.
Example:
Not a Fighter...but not a cafe-racer either. It's a little bit of both.
