Pictured above is my 1975 Honda GL1000 Endurance Special RC003. This bike is now Randakk's Cycle Shakk's test mule for R&D on high performance products for the GL1000. Many items are under development. For those who've criticized me in the past for being a GL1000 purist snob, your apologies are accepted!

This fabulous bike was originally fabricated by my friend Mike Barone. Mike is the National Director of the International CBX Owner's Association. Click here for more information on this great club. This bike has achieved near cult status on the Internet since its creation in 1999.

Mike and I share a common vision on the GL1000. This bike represents the design direction we feel Honda should have taken with the original GL1000. True to the original sporting inclinations Honda engineers pursued, this bike has it all: handling, performance and comfort. In the hands of a skilled rider, this bike is a track day and twisty road demon.

I consider this bike my Gentleman's Express...artful, yet deceptively fast...a modern-day Brough Superior SS100. This is the bike Lawrence of Arabia would ride if he were alive today. But, unless you're Jay Leno, a real Brough is beyond the reach of ordinary mortals ...click here for information on the real McKoy.

Mike and I have attempted to avoid going overboard on this bike. The focus is on function - not fussy attention to finish details. However, I happen think it looks great...very purposeful. The pipes are especially stunning. My bike could be duplicated at fairly reasonable expense by many enthusiasts.

Mike's son Aaron contributed his valuable expertise on the original project. Aaron is a master independent fabricator for NASCAR, Winston West and other race teams. He is an aero expert highly sought after for wind tunnel testing and superspeedway body fabrication.

This bike handles extremely well especially given its size and vintage....nimble but still a bit heavy; handles in turns.....never is last one home, passes more than a few current sportbikes in the twisties. Very predictable, neutral steering which inspires confidence.

Currently running this front brake setup: 296mm front brake rotor / dual piston caliper conversion:

For 2 riding seasons I used this EBC set-up (still using the rear):

• OEM calipers overhauled with heat treated, stainless steel brake caliper pistons
• EBC brake pads
• EBC Pro-Lite ventilated, semi-floating brake rotors front and rear for less unsprung weight. Fronts required minor machining of the caliper carriers for proper fit.

• VDO oil pressure gauge

• Standard oil filter conversion kit to allow "spin-on" filter: click here for details

• Since the addition of the supercharger, I'm now running a special oil filter adapter (to permit oil cooler) created for me by Bob Hagerman available here. Cooler is heavily-modified unit from '82 Honda CB900F. Also running a Think Automotive competition oil cooler thermostat (Mocal model #OT/2F-8JIC) connected via Aeroquip hoses with 8AN fittings.

• Bridgestone BT-45 Battlax V-rated tires
• Centerstand geometry tweaked for better cornering clearance
• Honda CBR1000RR footpegs and hardware (slightly modified)
