Methodology & Configuration
Scoring Process
  1. Collect Test Data: Gather results from professional tyre tests across multiple publications. Minimum 1 test(s) required.
  2. Normalize Positions: Convert test positions to percentile scores using exponential weighting (factor: 1.2).
  3. Apply Recency Weighting: More recent tests are weighted higher with a decay rate of 0.95.
  4. Incorporate User Reviews: Factor in user review data (minimum 5 reviews). Weight: 15%.
  5. Bayesian Smoothing: Apply Bayesian prior (score: 7, weight: 1.5) to prevent extreme scores with limited data.
  6. Calculate Final Score: Combine all components using normalization factor of 1.1. Max score with limited data: 9.5.

How many kms can this go?

Tyre wear can have a huge number of factors such as vehicle weight, driving style and surfaces driven on. I'd recommend looking through the wear ratings on the website to find an average for your own personal setup.

Given 81% while driving a Suzuki DRZ400SM (160/60 R17) on mostly town for 12,000 average miles
I'm not gonna review yall the cornering grip and such. Theres plenty here BUT what's not avail is the mileage of the tyre on a smaller bike.im weighing at 95kg and So tyyre actually lasted way more than 18000km on a DRZ400SM. My current odometer on was changed 1 month into owning this bike, so i'd say i would have probably reached 20,000km on this tyre. Or an average of about 1year 2 month for me. It actually would have been usable for a little bit longer, but tyre was wornout unevenly probably due to accelerating too much while leaning a little to the right, and some slidings when im feeling rowdy. Also had to ride a few KM slowly on flat tyre to find tube and that probably would have contributed to the uneven surface. This is the rear. The front still have loads of life in them and will probably last me a year more. Changed my rear to Rosso III at 18,746km and looking forward to reviewing it at the end of its life!

Given 91% while driving a Suzuki 1999 Gsxr750 (/50 R17) on a combination of roads for 2,500 spirited miles
I use these on a 99 gsxr750 and do very spirited riding. I’m very happy to get right at 2500 miles out of the rear. I have never gotten into a situation with these tires and are very confidence inspiring. Tires have a lot of feel and are excellent in the wet (for a super sport tire). I have absolutely no complaints, even the tread life! If you ride a little too fast or too hard, spend the extra money for your safety and piece of mind. You will never out ride this tire on the street and I find comfort in knowing I have some wiggle room when it comes to traction if a panic situation were to happen.

Yamaha (/55 R17) on mostly country roads for 0 spirited miles
I am now on my third set of Rosso 2's, and I could not be anymore disappointed than I am right now. Three sets in 2 years? First set, cupped after two months, second set, rear tire cupped less but front tire major cupping. Third set, less than a year old and the front tire is majorly cupped. After all of these years of promoting and pushing Pirellis for riders, I am going to have to bow out and go to a competitor.

Yamaha 2002 R6 (180/55 R17) on mostly country roads for 4,000 spirited miles
perfect for super sports of any size. great dry grip, but I never hooned in the rain, so I don't know. but they wear fast in the center. 4,000 miles on the rear before the center showed bands.

Given 77% while driving a Honda cb 600 f hornat (180/55 R17 W) on a combination of roads for 5,500 easy going miles
They lasted me 5 years and around 5500miles doing mostly city and a bit of highway and mountain roads. Both the front and the rear wore at the same rate with no obvious flat spots. Never had issues with the front, but the rear would spin really easily under acceleration and lock frequently under medium to heavy braking (no ABS). This started to happen more often in the second half of the tire life. I now have a new pair of Michelin Road 5 and they have more grip and stability in corners. But that's most likely due to the tires being new. Comfort-wise I find the Rosso 2 to be significantly quieter. I really like the Road 5 (200 miles on them). I think they are a better fit for the Hornet. At least for my driving style. The Rosso 2 are more aggressive and need a bit of heat in them before you are able to use them properly which I would rarely be able to do.

Given 80% while driving a (155/60 R17 H) on for 0 miles
fitted these on my duke 125 I loved them for the most part the only downside was in the rain the were not dangerous but the were not good either as for wear I had them on for 2 years and about 30ks I could not wear them out since road here are more like marble than tarmac I know changed them for the dunlop sportsmart2max seems to be better in the rain the front has a great feel but the rear is vague in braking at the limit and not that fast to lean other than that they took a lot of miles to brake in before they did they were horrible now they are good all and all I would suggest the rosso 2 for sportier more powerful bikes and the dunlops for more rain oriented riding and not seeking the ultimate grip levels and feel

Given 97% while driving a Yamaha YZF R25 (145/70 R17 H) on a combination of roads for 10,000 average miles
I cannot choose the right sizes that 110/70R17 and 140/70R17 where as perfect fitted to my Yamaha YZF-R25. Very good handling and grip performance on almost every weather and road conditions. Especially dry roads. I drove 16.000kms with first pair of these tyres and very satisfied. I bought new pair of Rosso II after 16K kms and replaced them with new Rossos.

Very good handling on dry, wet conditions almost all weather except very cool and dry weather. Strongly recommended for the size 110/70/R17 front and 140/70R17 rear.

Given 96% while driving a Ducati Monster 900ie (225/45 R17) on mostly country roads for 200 average miles
Early days on these Rosso 2 but they seem to compliment the Monster really well. Specifically purchased for their grip and dry weather performance. They seem to warm up quickly and provide excellent levels of grip I have no complaints at all and they compare favourably in price to the other major manufacturers offerings. They may be a little softer than other tyres and therefore wear quickly but then that's why I've fitted them. Not that you buy tyres for the way they look but they are pretty cool from that perspective too. Can't comment on wet performance, but if it's pouring then I'm in the car and the Monster's tucked up in bed !!

Given 77% while driving a (190/50 R17) on for 0 miles
Seen some reviews with crazy miles on them. This is not the case for me and my gen 1 zx10r, it's modded slightly and pulling 168hp at the wheel. I get around 1500 miles to a rear if I'm lucky. That's hard use on roads. I'm on my 3Rd set looking at the rosso 3 to replace them. I love the tyres. Great in the dry, very quick warm up, shit in the wet.

Given 74% while driving a Triumph Street Triple R (180/55 R17) on mostly country roads for 3,700 spirited miles
Bike: 2014 Triumph Street Triple R (standard bhp).

Riding Type: Dry roads with fast sweeping curves and tight twisties. Motorways, duel carriageways, in fact all straight roads avoided. Seldom commute or use city roads.

Superb dry grip, ok wet grip, very nice turn in, wears rapidly, good stability, predictable with good feedback, quite expensive given the wear rate.

A high quality grippy tyre for fast dry road or dry track day.

Mileage: 3700 miles

Given 89% while driving a Honda cb 600 f hornat (225/45 R17) on a combination of roads for 100 easy going miles
best tire i have ever put on my bike, and i have tried a few.
great Feed back and very soft for the road. and the best thing is that they heat up very quick. just a little slippery if not warm as all.
also did a 45km run of 100-140kph in heavy rain with a lot of confidence.

Given 71% while driving a Suzuki SV650S (225/45 R17) on mostly country roads for 6,000 spirited miles
A replacement rear tire only. My Dunlop Qualifier get destroyed by a large nail and this was the only tire in stock for my bike.

Good tire, it has dual compound and the sides are really sticky. Very good dry grip, and actually, not too bad in the wet either.

Wear was surprising good for a sports tire, got around 6000k which was more then double the Dunlop tire.

Would buy again? Maybe if I were taking a bike on track days, but switching to Bridgestone BT-023's for better lifespan.

Given 80% while driving a Triumph Street Triple R (180/55 R17) on mostly country roads for 3,000 spirited miles
Put these on my STR to replace the Dragon Corsa Pros that came as standard. This was a decision based more on budget than experience.

I have to say that I don't regret this decision at all. The grip is excellent and gives more confidence in cornering than the Dragons in my opinion.

I wouldn't say I ride at the ragged edge but I don't hang about and these tyres have performed consistantly and feel grippy and progressive. Most riding is done on A and B roads with a couple of longer runs and a short spell on the track.

I've put them predominantly to dry use but got caught out in some full on wet weather once and they still felt grippy.

My only gripe (and it is a small one) is that they don't wear as well as I'd like but then it's a trade off between wear rates and grip and tbh I'd rather have the grip. My Rear has lasted a little over 3000 miles and I'll be changing it shortly. I'll definitely use these again.

Given 74% while driving a Yamaha FZ6 (180/50 R17 W) on a combination of roads for 5,200 spirited miles
Lasted 5200 miles on my FZ6. Fantastic grip in the dry, never let go, even riding with guys on sportsbikes.
All I didnt like was front tyre profile was a bit 'pointy', meaning it turned in a bit to quick on a naked bike. When the tyres got to 4000 miles, the rear was fairly squared off, but the front had worn more at the edges, making turning in not that smooth.
I have this week changed to Bridgestone BT023, which make the steering slower, but suits my riding style and bike much better
