Dunlop Geomax MX32 and Geomax MX52 Review test rider Ryan Abbatoye flogged both Geomax models all day long at Milestone. Abbatoye found that while the MX52s are a huge improvement over the old MX51s, even the 52s can’t hold a candle to the MX32s, which delivered excellent feel, predictability and consistent traction regardless of lean angle.
