Product review: Dymag UP7X wheels

Senior Editor Matt Wildee has fitted a set of Dymag UP7X wheels to his 2000 Yamaha R1 and has covered around 2000 miles with them so far. To measure improvements, he went to the handling loop at Bruntingthorpe Proving Ground which features an 80mph right hander, a 60mph left and a 20mph hairpin. Perfect for measuring the gyroscopic effects and how much difference this has on direction changes.

What’s good?

These are some of the highest-quality forged aluminum wheels money can buy. Developed for racing (they’ve won in BSB and at the TT this year), they are also homologated for road use. At 4.40kg front and 5.56kg rear, they are 28% and 21% lighter than my 2000 R1’s stock wheels.

The resulting reduction of rotational inertia makes the R1 far more nimble than before, allowing it to change direction faster and giving it lovely, light steering. Stability has been perfect, too. According to my datalogger, this results in better acceleration and braking, and on track reduced my sector time though Bruntingthorpe’s chicane by 11%.

What’s not?

Honestly, they’re hard to fault.

Finish is strong with no chips or flaking and they come with beautifully-made captive spacers and anodized valves with fine-pitch caps. They aren’t a budget upgrade but they make your bike feel brand new. If you’re looking to upgrade to a new bike but struggling to spend ?15k, a pair of these would give your current 1000cc sportsbike a new lease of life.
