IMO the PR2's are the best tyres ever!
I use them on my K5 1000 and have had over 3200 miles out of the rear with a ride left in them as well. That's incredible for a full on litre bike which gets properly caned!
Had them on the Fazer too for a the last few sets before she got sold and couldn't fault them.
Bit pricy though.
I have just opened my own bike shop (round of applause....!) and we are currently doing a promotion on Metzeler Rennsports at just £150 a pair including fitting to the bike. Shop is around 30 minutes from Cardiff and just 10 minutes from the Brecon Beacons so maybe worth a run down for a pair followed by a great ride out to scrub them in....
Not sure what they will be like on the Fazer but they are usually a great fast road tyre and for that price, you can't really go wrong!
Sorry for the blatant plug.
