Pros, cons & observations
Themes extracted from owner reviews across retailers and review sites — not the opinion of TireWheelGuide.
The Bridgestone S20 is widely regarded as a high-performance tire that excels in grip and handling, offering riders exceptional confidence in both wet and dry conditions. However, this performance comes at the cost of rapid tread wear, with many users reporting significantly shorter lifespans compared to sport-touring alternatives.
Pros
- Exceptional grip levels in both wet and dry conditions
- Progressive and predictable handling characteristics
- Strong performance during aggressive road riding and track use
- Quick turn-in and confidence-inspiring feedback
Cons
- Very short tread life, particularly on high-torque motorcycles
- Rapid degradation and squaring off of the rear tire
- Front tire can be slow to reach optimal operating temperature
- High frequency of replacement leading to increased long-term costs
Observations
- High-torque motorcycles like the ZZR1400 experience extremely rapid rear tire wear, often requiring replacement in under 2,000 miles.
- Riders of lighter, agile bikes like the SV650 report better satisfaction with the tire's profile and handling characteristics.
- Track-focused riders noted that while the tire performs well under heavy load, it can shred quickly during intensive track sessions.
The Michelin Power GP is widely regarded as a premier hybrid tire, excelling in both spirited street riding and occasional track use. Users consistently praise its rapid warm-up time, exceptional dry grip, and surprising confidence in damp conditions, positioning it as a significant performance upgrade over its predecessors.
Pros
- Rapid warm-up time providing immediate confidence
- Exceptional dry grip and predictable feedback
- Superior performance in damp or wet conditions compared to competitors
- High agility and ease of turn-in
Cons
- Limited tread life, with some users reporting replacement intervals between 5,000 and 6,000 kilometers
- Potential for uneven wear or cupping on the tire edges
- High performance focus may not suit riders prioritizing maximum longevity
Observations
- Users transitioning from the Michelin Power RS to the Power GP on Yamaha MT-09 platforms report a noticeable step up in handling and stability.
- The tire is frequently compared favorably against dedicated track-focused rubber like the Bridgestone RS10 and Dunlop Sportsmart TT.

How do we compare tires?
Every category score blends two independent signals. 60% comes from professional tire tests (braking distances, lap times, noise measurements) normalized against the best tire in each test and weighted toward recent tests. 40% comes from thousands of owner reviews collected from retailers and review sites. When a tire has only one of the two, we use what exists and say so.
Community buzz from Reddit and forums is shown for context only — it never changes the score.
