Don't see why not. Some people will winge about API specs but the boxer engine isn't exactly state of the art so will do fine.

What does the handbook say
What the handbook says is based on BMW's knowledge when it was written.
What they say now is here.
"Castrol Power 1 Racing 4T 10W-50
JASO MA-2 API SL
BMW recommendation for Boxers,
HP2 Sport and K1200LT series"

Or are the current recommendations based on BMW being in bed with Castrol these days and under obligation to recommend products from their range?
Anyway, it looks like they recommend either 10w50 for 'ultimate performance' (there's a laugh) or 20w50 for 'trusted protection'. Either way, it would seem that 5w50 is not recommended - too 'thin' for boxers?
(if nothing else, I'd guess it'll make the engine clatter like a bag of spanners). For me with an 'x' thousand pound bike, I'd give the 5w50 to a mate with sports bike and shell out for some 20w50 (£15 aint the end of the world really)

5W/50 is only thin when cold. The hot viscosity (as denoted by the /50 bit) is identical to 20W/50. The fact that it is thinner when cold means it lubricates quicker from a start-up, ergo 5W/50 is better than 20W/50.
'ergo' BMW don't recommend 5w50 for some reason - you'd think they would if it was 'better'
viscocity modifiers for wet clutches?...

SO WOULD YOU USE THE 5-50 FULLY SYNTH OR WHAT?

NO!
DON'T BE A TIGHTARSE - BUY SOME 20W50 - OR PERHAPS YOU CAN FIND A BOTTLE OF OLD COOKING OIL IN A CUPBOARD AND USE THAT!

No because it'll make the engine sound like sh1te when you start it up.
Best use it on the capslock button

S'funny - my manual says "5W/50 - high end fully synthetic oil for use in all temperature ranges"

Yes, without question. A 5W/50 fully synthetic is better than a 20W/50 semi-synthetic.
Whether the bike needs the extra protection of the fully synth is a different ball-game. The only difference I could potentially see is at extreme mileages there may be less wear on stuff like cam lobes. The fact that these don't fail regularly even at high mileages suggests that the extra expense of top-end oils is probably not justified.
