Story By: Michael Allen The simple fact that more manufacturers are offering off-road closed course competition bike’s brings a smile to my face since at heart I’m an off-road lover.

Clutch KiT Performance

Rekluse Torque Drive Clutch Pack

I am hard on clutches. Why? Well…Instead of letting off the throttle when the front wheel starts to loft upward, I simply just slip/drag the clutch a little to modulate the power, so I can get to point A to point B in a faster manner, without letting off of the throttle. This way of…

Living With The 2019 Yamaha YZ250F

After being in love with the previous model YZ 250F, I couldn’t wait to get my hands on the 2019. Once the initial introduction testing was over I got to spend some real time on the bike and have been struck by cupids’ arrow (once again). Almost every aspect of the 2019 YZ 250F has…

2019 Yamaha YZ65/85 24 Hour Torture Test

At Keefer Inc. Testing we pride ourselves on riding the crap out of our test bikes. However, when it comes to smaller bikes, it’s not like I can Benjamin Button myself and ride 65’s/85’s. 1990 West Coast 125 Supercross Champion Ty Davis put together a Jr. 24 Hour Challenge Team for the 24 Hours Of…

2019 Yamaha YZ450FX First Impression

(Editor’s Note: Dominic Cimino is one of Keefer Inc. Testing’s OG test guys. In fact, I recruited him over at Dirt Rider when I was there because he was such a solid dude. He can ride a bike at a high level, is trustworthy, is no BS and his testing skills are good because he…
