Bikernet Baggers Visits Zippers Performance

By General Posts

I have been using Zippers Performance Products for a very long time and some of you may have seen one or more of the Tech Articles I have written about installing their products on my personal motorcycle or that of a friend’s.

Dan Fitzmaurice and I go back a long time, and I have met some of the people who work for Zippers at motorcycle events and shows around the country. But for one reason or another I have never been able to stop by their facility in Elkridge, Maryland.

Zipper’s Chain Drive For High-Output ’09-Up Touring Bikes

By General Posts



817-707_onbikeZipper’s cushion-drive chain conversion kit for 2009-up Touring models is for high output engines, with a modular design for strength and easy ratio changes. This kit is supplied with a steel front sprocket, a 7075-T6 aerospace aluminum rear sprocket, and O-ring chain (available in standard metallic, gold, or black). Our cushion-drive chain conversion kit is equipped with a chrome-moly axle and severe-duty slider-style chain adjusters, eliminating the cam adjusters. Conveniently, this system bolts-on and does not require modifications to the swing-arm. Contact Zipper’s today for any additional inquires about this kit.


Zipper's Hammer 88 big bore kit for XR1200

By General Posts

The Hammer 88 big bore kit maintains the engine stroke but converts the engine to a 'square' configuration by increasing the bore

Zipper's has now made a version of its Hammer 88 big bore kit available for use on Harley-Davidson's XR1200 Sportster.

The kit, which maintains the engine stroke but converts the engine to a 'square' configuration by increasing the bore, is offered in two versions; one with emphasis on the lower and middle ranges of power. For big torque figures, the other provides an emphasis on the upper end of the RPM scale creating big horsepower.

Each kit includes Zipper's aluminum big bore cylinders with cast-in ductile iron liners, Zipper's special 3-13⁄16in bore forged pistons, which are claimed to eliminate the need to rebalance the crankshaft, Red Shift cams, Pro-Taper cromoly pushrods and telescoping pushrod covers, and CNC-ported cylinder heads equipped with oversize valves.

The heads feature CNC-machined combustion chambers to match the pistons. Special hardware and a full gasket set are also included.

Finishing the kits off is the inclusion of high flow injectors, an air filter element and a pre-mapped ThunderMax EFI management module for simple plug-and-ride tuning.
