The 675 Daytona is really short on top end, so it has to be ridden to it's strengths: torque that gets it out of the slow corners, GP level steering and stonking brakes that make it possible to pass the only place it can against the R6. But..... it has problems that get exposed when you become genuinely fast on one.
You need to:
1 - fit a Triumph Rocket 3 oil pressure relief valve.
2 - fit a race sump gasket.
3 - dump the stock rear spring and fit an Ohlins, a 10 if you are between 75 and 85 kg.
4 - raise the triple clamps until flush with the top of the forks.
5 - remove the bumpstops at the bottom of the forks.
6 - change the front and rear sprockets for 15/45 you will be 16/47 at the mo, 520 is best, means the chain as well.
7 - fit tank grips for your knees to carry your body weight allowing your hands and arms to steer not brace on the bars.
The trail numbers on your model 675 are extreme and dangerous in the hands of the inexperienced at genuine fast corner entry. Raising the triple clamps and changing the rear sprockets alters the trail and lengthens the wheelbase, this massively improves mid corner stability and exit ( at the cost of just a little turn in) , removal of the bumpstops allows for much improved trail braking ( the front end valving and springs are good enough until you start running at the front, but the bumpstops are stealing 17mm of useful travel. The sprocket and chain change also allows you to spin the engine up faster and get out using the torque to drive. The re springing of the rear shock gets you compliance from the rear you will not currently have, wheel spin and instability are what the stock spring give you ( unless you weigh a 100kg )
Under hard braking ( not what a road rider thinks is hard braking though) the sump design has all the oil bugger off to the front and it can't be picked up meaning the engine can be scavenging frequently under hard use of the brakes.
I could go on for a bit, but I'll stop there for now.
I'll leave you with a pic of a multiple title winning Daytona.
