Now you can keep your stock arm just like it is and when you decide to go racing just bolt these on. Thats right! These bolt on to your stock arm and allow you to adjust your wheelbase lenght from 2" to 7" over stock for the hard launch you need to go fast at the dragstrip with out a big wheelie. When your done dragracing just remove these and your back to carving up the twisties. Made from T-6 6061 CNC aluminum billet block these are the strongest on the market. A extra feature that sets these apart form the others is these have the chain adjustments marks milled into them @ 1/4" adjustments...no more guessing...unlike the other copys cats on the market. The most note worthy feature that these have, that NONE of the others have is....the bolt in the picture... stays with the bolt on extension. The others on the market require that the bolt be shorter or longer when you move the axle. This means you have to remove and replace the bolt with different sizes. NOT THESE!!!! The bolt stays and allows the axle to move the complete lenght. Picture 1A shows how the is possible, the extra lenght of threads are hidden in the extension,inside the hole. Picture 2A shows the shape & taper of the block is kept to the factory look of the stock swing arm.

On October 16th 2004 John Noonan of JE Pistons set the World Land Speed record in the 1,650cc APS-BF (Altered Partial Streamlined Blown Fuel) class during the annual Bonneville World Finals. The Top timed speed reached on his 2001 Suzuki Turbo Charged Hayabusa street bike was an amazing 253.152 miles per hour! This speed was the average speed held for a mile and not just measured over a 132' timing trap like at other land speed venues.
John reached a top speed of 256 mph on the on-board GPS system before the end of the 4th mile when the charge tube blew off.
This fantastic 250+ mph run also earned John his coveted "AA" license, this makes John only the third person in history to achieve this tremendous feat at the big salt dyno in 55 years of Bonneville racing on a sit-down motorcycle
The average speed was a new World record @ 246.818 miles per hour! This Top speed record is the fastest in any of the motorcycle classes to date other than the fully enclosed Streamliners at the Bonneville salt flats located in Wendover Utah.
All of this was done on OEM street tires, OEM style AIRTECH bodywork, and a stock chassis other than an extended stock swing arm with 4"-7" swing arm extensions from SPENCER CYCLE.COM.
This is John's third year at Land Speed Racing and he already has set over 9 world records in the three yearly SCTA sanctioned racing event's he has entered at Bonneville. ( all records were set at speeds greater than 215 mph ) and 5 records at El Mirage Calif (racing in the dirt) with the fastest record being 232.311 mph.
John also holds the fastest record ever for a NON-streamlined (no bodywork) motorcycle at speeds over 220 mph done at El Mirage in the California desert dry lake bed in October -04. This record is faster than any other open non streamlined bike classes at any of the Land Speed venues Worldwide.
North American Record Annihilated at Jardine West Coast HP Dyno Shootout!
Long Beach, CA In a stunning end to an already record-breaking weekend, JE Pistons' John Noonan on his Suzuki GSX1300R Hayabusa land speed bike obliterated the existing North American record for horsepower registered at a Dyno Shoot-Out, Sunday, July 18, 2004. At 545 horsepower, Noonan surpassed the current record by 31 hp!
A crowd of hundreds packed the Jardine booth as Noonan arrived straight from El Mirage where he had set another record, Land Speed at 209.980 mph in the MBG-1650 class, just that morning.
THANKS JOHN and Congradulations on the WORLD RECORDS!
