Hook Up: QTM Oversize Front Rotor Kit
Application: All bikes (tested here on 2010 Kawasaki KX450F)
We love almost everything about the new 2010 Kawasaki KX450F. One of our only minor complaints about the big green machine is that it lacks a little power in the front brake department. Ask any experienced rider, and they will agree…stopping quickly and effectively is an important part of going fast around a motocross track. The stock Kawasaki front brake has good feel, but simply lacks overall binding power. At first, we suspected that our lines needed to be bled, so we pumped and pumped and pumped. Sadly, the feel at the lever remained the same, and we still found ourselves wishing for a more aggressive front brake. Next, we tried replacing the fluid with high-quality racing brake fluid. Still, we were left wanting.
Enter the guys at QTM. The QTM Oversize Rotor Kit consists of a huge 270mm floating rotor, and a hard-anodized 6061 billet aluminum bracket, which relocates the front caliper further away from the fork to accomodate the huge new rotor. Installing the kit took only a few minutes (we actually did it in the pits at the track) and before we knew it, we were back on the track. Unlike some aftermarket brake rotors that we’ve tested in the past, the QTM set-up doesn’t require you to use their own brand of brake pads, claiming that they work best. Instead, we kept the same partly worn stock pads in. Also unlike some aftermarket rotors we’ve tested, the QTM brake needed no break in time. Right from the first corner, the Kawasaki stopped on a dime. The feel at the lever is solid, yest progressive. One might worry about locking up the front wheel with a rotor this huge, but that is certainly not the case. The QTM rotor provides a lot more stopping power, but maintains the great feel at the lever. We love it.
– easy to install
– floating rotor resists bending better than a non-floating unit
– no break-in time required
– superb power and feel
– the round rotor is not as sexy looking as some fancier-shaped rotors
– we are actually going to have to remove the excellent QTM rotor for our upcoming 450 Shootout!
