If you want tires that can really bring out the maximum agility of your Ninja 300, look no further.

The profile on the Rosso II is a perfect compliment to the Ninja's light weight, making flipping the bike back and forth in the twisties almost completely effortless. The Ninja begs to be turned into corners with these tires, and once you're leaned over they'll keep you locked to the road with absolute confidence. I've pushed them pretty hard on the street, and never felt even a slight slip on dry pavement (wet is a different story).

I wouldn't expect to get high mileage from these tires, nor would I try touring on them in the first place. Wet grip is pretty poor (expect some slipping unless you pussyfoot through the corners), and I'm already seeing some tread wear after about 1500 miles.

However, if fun on the Ninja is your goal, you cannot do better.

For comparison, I recently swapped out the Rosso II's for Pirelli Sport Demons so I could do a 2,000 miles road trip comfortably. The Sport Demons were fantastic for touring for a lot of reasons, but they sapped a lot of the Ninja's natural agility, making the bike noticeably harder to throw around on the backroads (though still better than the stock tires). I'm looking forward to putting the Rosso II's back on and lighting up the curves again - the difference is night and day.

I ride a lot...and I mean a lot. I bought my current bike last year brand new with 0 miles on it. I now have 46,979 miles on it. That's not a typo.

I commute to work, and I hit the mountain hard.

For the mountain, these are by far the best tires I've used. The grip is INSANE. I have so much more confidence with these tires.

I even got caught up in a monsoon on my way home from work a couple of times, and I was still able to hold 90 with no problem.

The only downside is the mileage. I only got 3,300 miles out of these suckers. If you're looking for a good commuting tire that will get good mileage, I would recommend the Michelin Pilot Road GT 4's. They are my favorite for longevity.

I just ordered another rear Rosso II from RevZilla yesterday afternoon, and it was delivered this morning at 1000!

Have the thought in the back of your head that your stock tires just don't feel sticky enough?

Ever thought that maybe you should upgrade and maybe you'll feel better about the ride?

Well, look no further.

After looking at countless reviews for these tires, I was finally forced to buy some new ones, and boy did I pick the right ones.
These tires are ridiculously grippy. I literally feel like the ride has changed for me because of how much grip I feel I have. I feel much more confident about taking turns and corners with these bad boys now. I absolutely love these tires. Definitely recommend.

I went through 2 sets of these tires on my Ninja 250, both sets got atleast 6-8000 miles before needing to be replaced

These are very soft tires, but they handle very well in all conditions. Very progressive turning feel, you don't fall into corners, you glide in and out.

You will not be disappointed...

This tire has great traction and can't beat the price. The tire was exactly what we expected from the description on-line. I would recommend it.

These tires were the best upgrade i did to my 250. The difference was night and day. Just riding back from the shop the bike felt different. In a great way. If you bike comes with some cold hard cheap commuter tire, the upgrade to these is worth it. Hands down.

This new tyre from Pirelli is a winner! Awesome grip and stability. Great on the rain and at the limits. One of the best bang for the buck on motorcycle tyres. All the premium performance and quality and none of the crazy price.

I never knew a tire could make so much difference in a bike. I went from another big brand name company to this tire and the difference was night and day. Now all I need are knee pucks...

I ride a 07 sv650, which is my only form of transportation and therefore use all the time for various reasons.

I'm not giving this a perfect score because this is the first "high end" tires i have used, which means i can't really compare them to anything else. However, these tires are definitively better than other random tires i have used. I have used a set of rosso ii's for about 20k miles at the time, despite having gone through a lot of straights on the interstate, the tires have worn quite evenly. This may be because of the harder compound on the center. The front tire does seem ever so slightly more worn on the middle though. On twisties, the tires feel very planted on the road, given good conditions. Heck, it feels like i may be on a rail at times, if i need to brake during the turn, there's not much hesitation.

These tires have also done well during hard acceleration and braking. (thankfully) Heck, i haven't been able to spin the tire on anything but dirt, maybe i'm just not trying hard enough. On the rain, these tires have fared quite well, obviously you will need to tone down your riding on the rain either way, but i haven't felt scared when riding on the rain with these tires. They did great. The only time i had a small slide on the street was when turning over large a "keep clear" painting on the intersection, during rain.

I love these tires and will most likely use them again in the future.

Original lasted 9k miles. No reason to search out a new brand. Search wouldn't be long as there is not much made for a Diavel size rear...
