I'm the same on a Gen2 because that's what was on it when I bought it and I don't know any better. I'm interested to see what others run though and the reasons behind their choice.
I started out with nothing and I've still got most of it left

When I was at AP last week I asked griff what he considered as the best tyre size for my bike. He recommended 180/55 for a quicker turn in and general improvement in handling.

Gen2 running 190/55 for the quicker turn in reason mainly,plus the look of a FAT rear tyre
Some 190/55's rub the chain too as manufactures sizes are different.
Note: the 180/55-60 tyres are even quicker to turn in etc,but IMO the trade of is slightly less tyre on the surface at max lean(which I can only tell when on track) not as stable as the 190/55 etc

I've never tracked any of my apes so it's always 180/55 for me (gen1's)

For Gen1, 180/55 was Aprilia standard fitment on the R model with Ohlins and OZ and 190/50 standard on the base model. Unless you are tracking it and want to start playing about with geometry and maybe linkage changes as well as just damping and preload then I would stick to those options.

I never liked the 190/50 and always ran the 190/55 which I found to be a perfect road/track compromise.
The Dunlop Sportsmart in 190/55 came closest to chain strike and the Maxxis SportMaxx the furthest away (I ran these tyres for the last 3 tyre changes).
 
Im nothing special when it comes to road riding or track but was slower and less comfortable on the 190/55 it was slower to turn in on and always felt a bit wooden but the 190/55's made a big difference I felt I could turn in earlier and faster and get on the gas earlier .
 
Just my 2 penneth worth :-)

The 190/50 for me was always the tyre that was most noticeable, it actually felt flat and slow to react compared to the 180/55

As soon as the 190/55 came out i suspect most people switched to that on the litre bikes, i did and was more than happy on it but having gone back to the Aprilia i had completely forgotten how easy it is to throw one into the corner with a 180/55 on Big smile

180/55 for road, i'd like to think a 180/60 will work well too but have not tried one yet.

190/55 for the track purely because there is more chance of me actually needing that bigger footprint on there rather than the road Smile

I've had a gen 1 and gen 2 (gen 2 now) I could throw my gen 1 about easy and dropped into corners fast but I find my gen 2 very slow cornering, definitely doesn't drop in as easy. I'm not sure on the tyres on my gen 1 but the gen 2 has 190/50. What other size would help me out, 180/55?

190/50 are nasty and slow to react in comparison to a 180/55 which you probably had on your Gen 1, on a Gen 2 i would try a 190/55 and you should see a big difference, make sure you have the forks set the right height through the yokes too as that has a big impact on steering.

180/55 for Gen 1, 190/55 for Gen 2 :)

Cheers mate. I only bought the bike late last year so haven't been on it much but definitely felt the difference in cornering. There is also different tyres front and back which I hate so I might have to change them. Any recommendations on brand?

Tyre choice is very personal to be honest, me i steer clear of Dunlops :D (although some love the Roadsmart)

It also depends on what you want to do on the bike i suppose too, Metzeler M7RR get good reviews as do the likes of the Pirelli Rosso Corsa's, Michelin Pilot Power 2CT's are still going strong too and the Conti Road or Sport Attacks were a good tyre for me too.

Weigh up what sort of riding you are looking at doing and then go from there with your budget :)
