RAT-ROD RZR

-- A wild old-timer custom build -- By Casey Kramer Most of the builds we feature in Dirt Wheels magazine are all about the bling and the speed. This diamond-in the-rough XP 1000, on the other hand, was chosen because it caught our attention with its unique design and purpose. Being a mechanical engineer by trade, project owner Jonathan wanted something with style that would withstand his “work hard, play harder” mentality. The inspiration for the “Old-Timer” originally came from a love of classic ’30s-era trucks…

YAMAHA YFZ450 WITH 200 HORSEPOWER!

-- Hey wait, that's a 4-cylinder engine! -- Upon further review that's not a single cylinder engine. It's got 4 exhaust pipes and 4 intake tracks, so there's no way it can be a YFZ450 engine.

However he took the engine out and installed the engine from a Yamaha R1 street bike. Those 1000cc 4-cylinder engines make about 180 horsepower stock, and James figures his gets more like 200 with the…

THE MIGHTY QUADZILLA

-- SUZUKI'S 500cc MONSTER 2-STROKE QUAD -- Suzuki gets credit for coming out with the first quads as we know them today. First they introduced some little 4-stroke versions and then in 1985 they unleashed a high-performance 2-stroke machine known as the Quadracer 250. Suzuki gave us a couple of years to get used to that great machine and then in 1987 they totally blew us away with a 500cc version. Its official name was the LT500R Quadracer, but it was such a beast that everyone began calling it Quadzilla. You had to be a…
