I Ride: V4S and Ninja 400. Dichotomy.
If they have a directional arrow on them, they're directional belt design and should not be flipped. It's really that simple. CAN you flip them and "get away with it"? Maybe, maybe not. I wouldn't want to be the guy who doesn't get away with it and has my tire delaminate at high speed.

I have a really funny story about this involving a racing buddy of mine who ALWAYS flipped his rear slicks, science be damned! We were sitting at dinner in Indy one night after the MotoGP race when we were out with the Bridgestone engineers who were there doing tires for GP that weekend. So my "flipper" buddy was sitting right next to one of the engineers and another buddy was sitting across from them. Buddy #2 says to the engineer "I've heard of people flipping the Bridgestone rear slicks the opposite direction to get more life out of them, is that a good idea?". Buddy #1 gives him the glare of death, and then listens to an hour long dissertation from the engineer about how and why that is the worst idea anyone has ever had in the history of the world. It was priceless! Bottom line: don't flip.

Thanks guys, I think to be on the cautious side, I'm going to stick to keeping the Pirelli single directional. On a side note, those who run the multi directional Dunlops, what size do you use? They dont seem to be available in the oem 180/60ZR-17 size...

I use Dunlop’s that are bi-directional and flip them due to my home track being a heavy right hand track. No issues with the Dunlop’s but I personally wouldn’t flip them unless approved by the manufacturer.

Just had a conversation about this with a few track and race veterans... they flipped Pirelli with no issues...

But personally, I still wouldn’t do it. There’s a reason they kept it omnidirectional

Could that reason be to get more $$$ though since riders wouldnt be able to get the max life out of the tires. Conspiracy stories commence.

It could be legal based. No one wants to be on the hook for a tire that was flipped and then went boom!

Nobody cares on flipping the rear up here in the north,including myself. Seems to be quite common that the front is flipped also,among top racers/trackdayers.
Another tyre issue with the new superbikes like the v4 and r1 is that they have so much grip the tyre rotates on the rim..

Awesome thanks! Anyone care to give their review on the N-tec's or compare them to Pirelli superbikes?
