Dunlop Sportmax GPR-300

My stock rear is done. As I'm using the Duke as a commuter more lately, looking for a reasonable tire that is still retains some performance. The Dunlop Sportmax GPR-300 looks to be a good fit. Has anyone tried this tire?


BTW, I would be getting a 140/70 rear

I almost bought one last week, but went for the Bridgestone as I'm not so concerned about tyre life, and it was a good price,
But the dealer recommended the Dunlop or Bridgestone, and I believe they are standard on the BMW G310.
If I was commuting I would have gone for the Dunlop.

Out of curiosity, how many miles (or km) did you get out of the stock tires?

1988 Kawasaki ZX10
1996 Aprilia RS250

are you referring to the battlax hypersport s20? if so, i'm now also considering this tire as it's around the same price point as the gpr 300's.

I'm around 5500 miles and my rear tires is done which is lower than expected. I ran oem tire pressure when commuting but went slightly lower when doing spirited runs in the canyons. Most of my miles are commuter miles. Front tire still has plenty of life.

Yes, Battlax S20 EVO, it was actually a bit cheaper surprisingly.
Did you see the YouTube Revzilla reviews on both?

did you wear out the center section, or did you wear it out evenly?

different riding styles will wear out tires in a different way clearly.

Another tire to look at is the Dunlop Alpha series. They are supposed to have a harder center section for longer life when commuting and softer side sections to give more grip when leaned over. they are also supposed to be great in the rain.

as i'm using the duke mainly as a commuter now, the centers wore much faster than the sides. however, the center didn't wear evenly. at around 5,300 miles i noticed portion of the bands were exposed. this is with 29 psi cold.

anyhow, i decided to give the bridgestone s20 a try. while it still may not be the ideal commuter tire, i still want a tire that is track capable as i still would like to take the duke to the track. ideally, getting another set of wheels for track and commuter setup would be ideal.


btw, i also went with the 140 rear.

inaugural ride with the s20's today...love them! as mentioned by others, the 140 has a much better profile. the duke feels much more nimble and planted as the tire's profile is not distorted. can't wait for a spirited run in the canyons and a track day.
