Hi Max yes it is way too early unless it was abused.
I traded my '04 Sprint ST 955i at 75,000kms and this was ridden very hard and often very hard two up.
When I traded it for my 2011 Sprint GT the old 955i still ran like a top, zero clutch slip and very minor oil use, 200ml per 5000kms.
I only have ever run all my Triumph Triples on good quality semi synthetic oils and change this out at 5000kms.
But that is what your symptoms sound like.
If it were my bike I would not bother fitting any clutch components that require more lever pull than the bike has as stock.
The Sprint 955i gen 2 clutch works just fine with the standard components and lasts a very long time under a lot of hard work. This is my opinion.
But that is just me, I am not a weakling and am built like a bull and wear size XXXL motorcycle gloves.
You do not need heavier clutch components for normal road or the odd track day use.
I believe a heaver clutch pull would become annoying especially if you do much city riding like commuting.
