I have not fitted Evotech but have fitted ASV's to mine. All levers are similar when fitting. They were easy enough. Just need to ensure you disconnect the clutch cable from the engine side to ensure you have enough slack to disconnect the old to fit the new. Make sure you have some free play in the new cable to ensure you don't get a slipping clutch at high revs. I suggest to take pictures of the clutch end (engine side) where the locking nuts are to ensure you put them back to the same place along the threads to ensure iyou have minimum feck around factor when fine tuning once fitted.
I fitted EvoTech to my old Speed Triple R (16 plate) It was a bit tight but worked well once on. Good feedback, adjust ability was good and looked the part, especially with the red adjuster matching the red on the R
ok picked levers up from biker bits in Seaford £100 ,actually cheaper than evotech sell them for ,quality looks good no hassel fitting just need to get out and try them now
tried levers yesterday and they are lush once I got used to them ,(a few stalls)but I can actually get my stubby cocktail sausage fingers around them ,def thumbs up
