You can do the following to lower the bike:

Loosen the triple clamps and slide the fork tubes up. How much you can "get away with" depends on a lot of factors; usually 1/2" is ok. I've seen it done as much as 1.5", but that was pretty radical.

Look at the rear suspension. If it's "linked," there are probably two "dogbones" that connect the swingarm to the shock/spring. Those can be replaced with shorter versions. Anywhere from .25" to 1" is possible.

Does the bike have a preload adjustment? Most do, and you can get 1/2" lower out of most of them, assuming it's fully extended now.

I'd find a Triumph Daytona forum and scan that for more detailed answers. I'm sure somebody has done this somewhere and posted info about it.

Need longer "dogbones" to lower the back of the bike.

As The Spaceman was saying, you can do many of these things - but I caution you not to "overdo" it: On the front - if you raise the forks in the triple, be certain that the wheel/fender will not contact the front of the bike (engine, radiator, fairing, etc.) on full compression. Same with the rear suspension. You may need a BIG friend (or two!) to help find the limit - but, rest-assured - if you CAN make parts touch at a standstill, they WILL collide with some force on the road, and when you most-need stability (i.e. a pothole).

I also advise that you keep a slight "forward rake" to the bikes attitude: with the front ever-so-slightly lower, that promotes stability under acceleration. At the very least, do not get the rear lower than the front, if you can at all help it.

Preload is for setting "sag" - and if you've too much sag (or too little) for your weight, it can adversely-affect handling. It should not be used to adjust ride-height, other than to compensate for non-standard loading (i.e. a passenger, luggage, etc.).

One other "trick" is to remove section of foam from the seat,or replace it entirely with a thinner-section of denser foam. You can even do this yourself, if you're "handy". A cheap electric carving-knife makes an excellent tool for "sculpting" seat-foam, and there is plenty of takeup on the bottom of the seat (you'll note the cushion-cover is likely just stapled-on, should you invert your seat and observe it's secrets).
