TypeSport / Street

FitmentFront & Rear

Sizes9

Jointless Band (JLB) rear construction winds a continuous belt for a uniform contact patch — smoother cornering transitions and more consistent feel through every corner

Advanced belt geometry sharpens steering response and keeps the bike stable mid-corner without requiring a track-spec compound

Sport-derived tread pattern pulls double duty: aggressive enough to look the part, functional enough to shed water and grip on mixed street surfaces

Casing tuned for lightweight sport and naked platforms — the feedback loop is dialed for 300-400cc bikes, not masked by excess rubber

Balanced compound strikes a real compromise between street grip and wear life — you get both, not a trade-off weighted entirely toward one

Wide size range covers the most popular small-displacement sport and naked platforms, including the Ninja 400, YZF-R3, KTM 390 Duke, CBR300R, and DR-Z400SM

Best For

Sport Commuter

You're putting real miles on a lightweight sport bike — commuting through Orange County traffic during the week, maybe stretching it out on the 241 or up Ortega on weekends. You need a tire that handles wet pavement and doesn't need replacing every few months. The GPR-300 was built for exactly this routine.

Perfect Match

Canyon Carver

You push pace on twisty backroads and want a tire that talks back — clear feedback, confident lean angles, no guessing. The GPR-300 delivers the responsiveness a sport rider expects without the short lifespan of a track-biased compound. It won't quit on you after a hard canyon run.

Great Match

Track Day Regular

If you're spending multiple weekends a year at Streets of Willow or Chuckwalla pushing intermediate to advanced pace, the GPR-300 isn't your tire. It can handle a low-key intro track day, but its strengths are on the street. Step up to a dedicated track tire that can handle heat cycles and sustained pace.

Consider Dunlop Sportmax Q5 or similar track-oriented sport tire

Frequently Asked

On a lightweight sport or naked bike used for mixed street riding, most riders see 5,000–7,000 miles out of the GPR-300. Hard canyon sessions and track days will pull that number down; disciplined commuting can push it higher. It's one of the better-wearing tires in its class for street use.

The GPR-300 can handle a beginner-level track day at moderate pace without issue — it's a capable sport tire. But if you're running intermediate or advanced groups, you'll outpace what this tire was built for. A dedicated track tire like the Dunlop Q5 will serve you better where heat resistance and outright grip matter most.

Jointless Band construction uses a continuously wound belt rather than overlapping belt strips, which creates a more even contact patch around the full circumference of the tire. In practice, riders feel more consistent feedback through corners and less vibration at highway speeds — it's a real-world difference, not just a spec sheet bullet.

Yes — plan on 50 to 100 miles of moderate riding before you lean into it. New tires carry a mold-release agent from manufacturing that needs to scrub off, and the compound needs to properly seat against the casing. Keep the lean angles conservative, brake early, and build up gradually. It's basic tire care that applies to every new set.

Dunlop engineered the GPR-300 for small-displacement sport bikes and middleweight nakeds — think Kawasaki Ninja 400, Yamaha YZF-R3, KTM 390 Duke, Honda CBR300R, and similar platforms. It's also a well-known fit for the Suzuki DR-Z400SM supermoto. If you're not sure your bike is covered, call MTC at (714) 516-9059 and we'll confirm fitment before you order.

The GPR-300 holds up well in the wet for a sport-category tire — the tread pattern is designed to move water out of the contact patch and maintain grip in the kind of mixed conditions SoCal streets actually deliver. Dedicated sport-touring tires may have a slight edge in heavy sustained rain, but for typical wet-weather riding the GPR-300 gives you genuine confidence, not just dry-weather performance with a disclaimer.
