Ive yet to try the gen 4 can we have a diluted pros and cons on the gen 4 over the gen 3 from those who have had both ? Does it warrant the change for the money?
Be interesting to see others views. Bought my Gen 4 in June and is my first BMW bike. I’ve recently had it on track at Alcarras for 3 days and was blown away by it so much that I’ve sold my Ducati 899 Trioptions track bike and bought a gen 3 track bike. I won’t get a chance to ride it until February at Jerez so would be nice to see others opinions.
Does it have oe sussies or aftermarket ?

The Gen 3 felt like a bus compared to the 4, steering and tip-in are worlds apart. Torque is such that 6th gear on the 4 feels like 4th on the earlier bike - which itself was no slouch in the mid range. The 4 doesn’t seem to have that scary top end because it’s got such strong performance lower down, so no big leap at 12k. I preferred the riding position of the 3, more sit-in. Suspension on the 4’s much more refined. TFT and its additional functions are a clear, huge improvement. New model’s much much easier to go quick on without the level of drama that came with the earlier one. I can see that many people might prefer the drama though! 4 sounds crap compared to the 3, worth repeating - crap, even with an end can. Which do I prefer - my new M, absolutely no contest.
Your feedback on the sound saddens me

I stuck an Akrapovic end can on mine, disconnected the exhaust valve - sounds good now.
Ordinarily the valve I believe is shut until higher revs due to noise brigadePlease explain to me the function of the exhaust valve and how does it benefit the sound by disconnecting? Thanks.

If you look at the link pipes between the cat and the end can, you will notice their are 2 pipes - one wider than the other.
A valve completely closes off the wider pipe at low revs and partially closes at medium revs. When the exhaust gases are restricted to flowing through the smaller pipe, the sound is significantly reduced.
If you disconnect the valve (by unhooking the servo cables), the valve remains permanently open - so the exhaust sound is unmuted throughout the entire rev range.
Does this throw up any dashboard errors?
