Dunlop Geomax MX32 and MX52 Tires

We finally had the chance to experience what motocross riders have been enjoying for the past year or so with the launch of the Dunlop MX52 and MX32 motocross tire. These tires have been a part of 62 wins over the past motocross season, but can that success translate to everyday riders?

What’s New
The new Geomax MX32 and MX52 tires replace the old MX32, MX51, and MX71 models in Dunlop’s motocross tire range. The MX52 has a tread pattern that is a little more suited to intermediate and hard-packed terrain, while the MX32 is more geared toward soft conditions.

One of the biggest innovations that has helped achieve such success is Dunlop’s new block within a block design, is their Progressive Cornering Block Technology (PCBT). Through their extensive load testing, Dunlop found that the external portions of the knob carried all the pressure while the interiors bore almost none. Many of the motocross tire companies have played with the idea of cutouts within the blocks of the tires to help provide a more even contact patch while leaned over with little to no benefit. Dunlop found that, by elevating the interior of the block, they could design a tire that was still good at aggressive starts and straight-line performance while drastically improving the tire’s performance when leaned over.

Dunlop has also made advancements towards improved handling and knob durability by providing more flex which translates into less knob tearing. This has been achieved by the knob’s recess carcass design. They’ve also changed the rubber compounds in the sidewall slightly to provide better bump absorption.

The Ride
We spent a day riding on both the MX32 and MX52 at Milestone MX Park in Riverside, California. We arrived early to a short briefing delivered by both the designers of the tire, as well as the head riders from Dunlop’s test track while the Dunlop race team fit our bikes with new Dunlop rubber.

I spent the first half of the day on the harder packed Veteran track, riding the MX52’s. These feature a center staggered block design on the front tire, which is supposed to help the tire absorb impacts, and the blocks on the rear tire are slightly larger while being spaced slightly closer together for increased surface area.

For the second half of the day, I tried my hand at the main track with the Suzuki RM-Z250 now fitted with the Geomax MX32 front and rear. While I definitely felt a difference between the two tires, I also felt like the worst person to ever ride a motorcycle compared to the press from dirt-centric magazines. Riding motocross is all about being fluid and gapping things correctly, something that’s really difficult if you’re fairly new to the sport.

Since I had just flown in the night before from The One Show in Portland, Oregon, I didn’t have time to go pick up a bike, Suzuki was kind enough to send staffer/all around bad ass Frankie Garcia out with a few bikes for us to test these tires with. Frankie used to be a test rider before he went to work for Suzuki and is good at everything on two wheels. Like, really good. We here at RideApart love off-road adventuring but, given that we’re fairly new to the dirt track – I’ll defer to his expertise.

    You guys should write a MX beginner guide. I really want to ride MX, but don’t want to deal with the crazy double jumps. Are there any tracks in SoCal with only table tops?

      Great idea. The short answer is to try vintage MX. Old MX bikes are super crazy extra cheap (like $1k) if you shop right and the racing itself is much lower pressure. It’s just a fun day out riding in the dirt.

        Or a modern DS bike which should be as capable as a vintage MX but legal/ridable everywhere.

        Was originally hoping this was a DOT off road tire review. If you want controversy, search under “best off road DS knobby tire that does everything”.

        There’s no way I would recommend starting MX on a vintage bike. Newer bikes are light years ahead in the suspension department, which makes them much safer to learn on. Going long on a jump or coming up short can have major consequences. Newer, full on MX bikes have a built in safety net when it comes to suspension. You can’t read a book or get advice on learning the timing of jumps. The only way to learn is to get out and start jumping. I started on street bikes at 18, have road raced and done 50+ track days, and got into MX at 27. There is very little that transferred from the street/road course to dirt. Having a bike with good quality suspension saved my butt many times. You can buy a mid 2000s 125 for less then 2k. Make sure the bike is up to date on maintenance and go have a ball.

      Clint there are several tracks in So Cal that have Vet tracks. Very safe but fun layouts….

    Wes really let himself go according to that first pic

    I think it’s a great idea too.

    I’ve introduced a few road riding buddies into mx and can say If you’re serious and keen to ride (and perhaps race) mx just buy a 250F and jump in the deep end. Most tracks (where i’m from anyway) have novice sessions where you won’t have to worry about riders landing on you. Also.. join the gym and get fit… man what I would pay for someone to go back in time and tell me that 10 years ago!
