Quick verdict
Pirelli Diablo Rosso III 120/70 ZR17 58W looks like a size-matched shortlist candidate for riders who already know they need this exact fitment. It is not backed by a strong visible owner-review consensus for this exact size, so the safer approach is to compare the current price, stock and delivery on Tyres.net before ordering.
Available tyre sizes and prices
Diablo Rosso III 120/70 ZR17 58W is listed with 4 tyre size options from £111.10-£118.61. The visible tyre sizes include 120/70 ZR17 58W, so use the table to compare the option that matches the exact size, colour, format or specification you want. Always confirm the final checkout price, delivery charge and stock status on the retailer page.

What is confirmed from the listing
The confirmed details point to a Pirelli motorcycle tyre in the exact 120/70 ZR17 58W size, with Pirelli’s own technical material also listing the same Diablo Rosso III fitment. Tyres.net’s live product page could not be read directly because it returned a blocked page, so the retailer-facing price, stock, delivery and any extra specification should be checked again on the live listing.
What the wider comparison suggests
The tracked price range for this product is £112.74-£122.37, which sits close to the comparable-market median rather than standing out as unusually cheap or expensive. There are 4 tracked variants, which is above the median for similar motorcycle tyres, but the visible owner review evidence is thin, so this reads more like a shortlist option than a proven review-led winner.
Buyer trade-offs to think through
The main trade-off here is between exact fitment confidence and limited public feedback. If your bike requires 120/70 ZR17 58W, the load index 58 and speed rating W matter more than broad Pirelli reputation; if you are comparing alternatives, check season, tread purpose and whether the retailer lists wet grip, noise and fuel-efficiency labels for a clearer side-by-side view. The supersport/street wording is best treated as use-case context, not independent proof that it will suit every rider or every road.
Price and value benchmark
At £112.74 at the low end of the tracked range, this tyre sits near the middle of the comparable market for motorcycle tyres rather than at a clear discount. That means value depends less on chasing the cheapest listing and more on whether the live Tyres.net price, delivery charge and stock line up with the exact specification you need.
How the specification compares with nearby options
The important check is not just Diablo Rosso III branding, but whether the exact 120/70 ZR17 58W size matches your bike’s placard or current sidewall. Compare the load and speed rating, any wet grip or noise label values shown on the retailer page, and whether nearby alternatives such as Pirelli Angel GT in the same size offer a more suitable tread purpose for your riding.
Why the review details are cautious
There is no meaningful owner-review count visible for this exact Pirelli Diablo Rosso III 120/70 ZR17 58W listing, so the lack of review volume should not be read as proof of poor quality. It mainly means product-specific feedback is limited, and the blocked Tyres.net page leaves the live retailer details unverified until you check them yourself.
Who it suits
This tyre suits riders who already need the exact 120/70 ZR17 58W fitment and want a supersport/street category tyre from Pirelli’s Diablo line. It is most useful when you are comparing options for a known front tyre size and want to keep the decision grounded in specification, price and live availability rather than broad brand reputation. The supersport/street label helps frame the intended use case, but it should still be matched against your own bike and riding needs.
Who should avoid it
Avoid assuming this Pirelli Diablo Rosso III will fit if your bike needs a different size, load index or speed rating, because tyre fitment should be confirmed from the bike placard or current sidewall. It is also not the easiest choice for shoppers who want strong product-specific owner-review backing, since the visible review evidence for this exact 120/70 ZR17 58W size is limited and the retailer page was not directly readable.
Comfort, grip and efficiency labels
For a motorcycle tyre like the Diablo Rosso III 120/70 ZR17 58W, the most useful comfort and support clues are any road noise, wet grip and fuel-efficiency labels shown on the live Tyres.net page. Those labels can help you compare this Pirelli against nearby alternatives, but they remain specification cues rather than proof of real-world ride comfort or active performance.
Value check
Value here comes from a correct size match, a sensible mid-market price and the usefulness of the live spec sheet, not from any strong review volume. With 4 tracked variants and a tracked range of £112.74-£122.37, it is worth considering if the live retailer page still shows good stock and a checkout total that works for your budget.
Good alternatives to compare
The closest alternatives to compare with Diablo Rosso III 120/70 ZR17 58W include Scorpion MX 32 80/100 D21 51M, Scorpion Rally 90/90 D21 54R, Diablo Rosso III 140/70 R17 66H.

Questions about this tyre
Is the Pirelli Diablo Rosso III 120/70 ZR17 58W the exact size I need?
Only if your bike’s placard or current tyre sidewall specifies 120/70 ZR17 58W. Do not assume compatibility from the model name alone, because the load index and speed rating need to match what your motorcycle requires.
How should I compare this tyre on price and availability?
Compare the live Tyres.net price against the tracked range of £112.74-£122.37, then check stock and delivery before checkout. A tyre in the right size is only a good buy if the final price, delivery cost and availability still work for you.
Does the tyre’s supersport/street positioning mean it suits my riding use-case?
It gives you a useful category clue, but it is not proof of performance for your own riding. Treat the supersport/street wording as context for comparison, then check whether the exact 120/70 ZR17 58W size, load index 58 and speed rating W suit your bike and intended use.
What do the load index and speed rating mean on this listing?
The load index 58 and speed rating W are part of the tyre’s required specification. They should be matched against your motorcycle’s own requirements, because the right width alone is not enough if the rating does not suit the bike.
Why is there so little owner-review evidence for this exact tyre size?
The visible review details for this exact 120/70 ZR17 58W fitment are thin, so there is not enough product-specific owner feedback to make strong claims about wear, wet-road behaviour or long-term value. That does not prove a problem; it just means you should rely more on fitment and spec checks.
