This month a 2001 Honda CBR929RR gets freshened up. Though this rig represents a clean example, it's still nine years old and in need of an update. Since it was previously equipped with motor mods and a 520 conversion, we're not looking to extract any more power. Instead, we're looking to drop some weight and preserve the existing power. It may not have the outright stomp of the new literbikes, but with a few tricks it'll be nipping at their heels.
For $89.99 you get everything...
For $89.99 you get everything needed to keep temps cool. It installs easily and makes a huge difference-bikes should come from the factory like this!
In addition to excess weight, heat is a serious performance killer so we'll be starting with an XS Boost Performance Fan Control module. Most sportbikes run hot as a result of their small radiators and limited coolant capacity, and the 929 is guilty of said ailment. One might think sufficient cooling capabilities would top a sportbike designer's list, but in actuality a large radiator and substantial cooling capacity result in tons of weight-the last thing you want. But when heft is decreased, coolant temps are increased. Since there isn't enough liquid to cool the motor, when sufficient air (above 35 mph) isn't passing over the radiator the coolant temps start rising and the power starts to fade.
We've all been there, sitting in traffic as the temp gauge starts creeping skyward. Once over 200-degress there's no turning back because by the time the factory settings activate the fan, the bike is boiling hot. But thankfully, XS Boost Performance stepped up with a cool fan mod that's a must-have for any street rider.
The fan controller allows you to control the factory fan with a discreetly mounted switch. If that's not cool enough, the fact it installs without any cutting makes it a winner.
In the real world the fan controller is crucial to the 929's existence. Whenever air temps make the motor run warm a simple flip of the switch brings it right back down. After using the XS Boost Fan Controller for a few weeks we don't know how we survived without one.
