Billet Engine Cover description

Integral "Frame" Bumpers!

slider concept patented

These are NOT the overpriced, poorly detailed covers that Lxxkxxxt and and others make and sell - they are hand deburred, countersunk, beveled and radiused to a detail level that makes any other cover look like cheap and tawdry copies....

Actually - one of those covers IS a copy of our gasket profile! But they didn't go through the exterior detail effort and the CAN'T do the pat. pend. slider.

A 100mph lowside will likely wear through a non-slider equipped billet cover. At least, the cover will become an ugly scar.
With the Factory Pro cover - all you would likely need to do to erase that 100 mph "event" is to simply unscrew 2 screws and replace the slider!

Integral "Frame" Bumpers!

Remove 3lbs from the end of your crankshaft and gain much acceleration - just like the old ACM Kit for the FZR400/600. This cover is tucked in MUCH closer to the engine for maximum cornering clearance when racing.

Not for street use unless you want to recharge your battery every hour or so....

BOTH sides Integral Crash Bumpers tested at NASB Daytona! By 1 rider!
The bumpers protected not only the bike, but even kept the engine covers mostly off the asphalt track!
Other part of story? The other racer on the team lowsided his R6 on the left side, ground through and broke the stock cover, destroyed the cover, the stator, hit the rotor and, more than likely, bent his crankshaft and warped the engine cases - basically, he's buying a new engine.
$400 worth of covers.....He'd still be racing.

Other part of story? The other racer on the team lowsided his R6 on the left side at 30-35 mph, ground through and broke the stock cover, the stator, hit the rotor, bent his crankshaft and warped the engine cases -
He bought a new engine.
With $400 worth of covers.....He would have still been racing - that day.......

  • Absolutely the strongest cover you can buy.

  • Highest strength / weight ratio available!

  • More clearance and cover thickness than stock on both RH and LH side covers.

  • Visible on both sides.

  • Can be show polished to a mirror finish!

  • Includes: Gaskets and replacement stainless steel allen screws when required.

Even without the included upper bumper installed - 3 hits in 1 morning and still going strong on Reuben Xaus' R6
The stock cover will easily grind through in 2-3 "low sides" causing dangerous oil leaks.

The covers remain!

Dear Marc,

Sorry it took me so long to get this email to ya. have been busy...

Just wanted write and tell you I got a chance to test out those crash bumpers. It worked so well on the right side of the bike, I thought I might as well try the left side. No worries they work, great saved a lot of bodywork damage as well as saving the frame from getting all scuffed up. It didn't even grind'em down to the bolts.

I got some Factory pro certificates en route to ya. They should get to you by Wednesday.

I also wanted to thank you for helping me AMA weekend in Brainard, and for all the technical support over the phone.

Thanks for everything,

Robert Jensen

The extension of the laboratory for engines of the Swiss Federal Institute of Technology was completed in about 1935. Its architect was Rudolf Otto Salvisberg (1882-1940). He had a successful career in Berlin but returned to Switzerland after the advent of the Nazis. His architectural style was somewhat similar to that of Erich Mendelsohn. The staircase of the laboratory is in normal use but well preserved.
