 With a name unmatched in the 4-stroke and 2-stroke markets, Wiseco’s forged aluminum pistons have a reputation for improving engine performance. Virtually all the top teams in pro MX and off-road racing choose Wiseco as “the source” for boosting engine performance and improving reliability.
Wiseco Piston even sponsors several of the top off-road racers in the U.S., including Ty Davis, Rodney Smith and Steve Hatch. Want to know a few of their “secrets” for speed? Ty Davis uses Wiseco #4693M09500 and #4693M09700 pistons on his Yamahas, and the Suzuki DRZ400s ridden by Rodney Smith and Steve Hatch use #4714M09000 and #4714M09200. (But don’t tell ‘em we told you!)
Wiseco’s humble beginnings in the off-road market date back more than 60 years, when Clyde Wiseman cast and machined pistons for his speedboat’s outboard motor in his garage at home. He went on to establish Wiseco as the leading manufacturer of quality performance 2-stroke motorcycle pistons, and in the process gained Wiseco a reputation for high-quality, forged aluminum pistons. Today, Wiseco pistons are used for all forms of motorcycle competition and recreation, as well as NASCAR, Indy Car and NHRA drag racing.
Why use forged aluminum pistons? It’s simple: because forged pistons are lighter than most cast or hypereutectic pistons, they enable the engine to rev quicker with less stress and ultimately provide an immediate gain in performance. And, as heat retention is minimal, the engine operates at cooler temperatures. The piston also can withstand increased loads, even with higher compression ratios because the denser, forged material is formed into shape under 2,000 tons of pressure.
Why go with Wiseco? With slightly higher compression ratios, Wiseco pistons can even further improve your engine’s performance. Computer designed with diamond-turned piston skirt profiles to help reduce friction, the pistons’ wrist pin holes are reamed for a near-perfect fit for the straight-wall, heavy-duty chromed wrist pins. And, wrist pin circplips are provided as well.
