Choosing a sport-oriented street tire set for your motorcycle is a balancing act: you want cornering grip, but you don't want to give up everyday mileage; and you need wet-road confidence without sacrificing dry performance. For many riders, the answer comes down to how much time you spend at full lean versus how many highway miles you pile on. The Pirelli Diablo Rosso II front and rear set is designed around that trade-off, with a dual-compound rear tire and a functional groove pattern aimed at wet-road behavior. The key question is whether this front and rear combination makes sense for your bike and riding style.
Quick verdict
If your motorcycle runs the exact front and rear sizes this set uses, this two-tire set at USD 289.99 is a compelling sport-street package. The rear tire's harder center compound and softer shoulder compound are aimed at balancing straight-line wear with cornering grip. The front and rear are load/speed rated 58W and 73W, respectively, aligning with the ZR speed designation in the tire size.
Who it suits
This set is tailored for riders who spend most of their time on paved streets and want a tire that behaves well when leaned over. The slick shoulder area is designed for maximum grip at full lean, which rewards riders who enjoy aggressive cornering.
What stands out from the listed details
Pirelli's Integrated Contour Shaping (ICS) technology is intended to help maximize the contact patch area, supporting confident cornering. The set's functional groove design is meant to optimize wet behavior, so you can keep riding when the road gets slick. It also comes as a front and rear pair, so you don't have to source tires separately.
Meaningful trade-offs
The set is a fixed 120/70ZR17 front and 180/55ZR17 rear pairing, so it suits a motorcycle that uses these dimensions. If your front or rear size differs, these tires won't be the right fit. The load and speed ratings are also specific to this set, and the design emphasis is sport performance for everyday road use. Because it's a two-tire set, you're buying both ends together, which simplifies the purchase but removes flexibility if you only need one tire.
Bottom line
At USD 289.99 for the pair, the Pirelli Diablo Rosso II set gives you a front and rear tire pair with an eye toward grip and everyday road manners. If your sport street motorcycle uses the exact sizes in this set, it's a solid way to get confident cornering and practical street performance in one purchase.

The concrete reason to choose this set is the way it packages sport-focused features into a single purchase: the tires are a matched pair, and the slick shoulders are aimed at full-lean confidence. The limitation is the fixed sizing - if your bike's front and rear tire dimensions don't align with the 120/70ZR17 and 180/55ZR17 pairing, this front-and-rear set won't fit.
