Gas’d Rat. A Rocket Chopper.

rocket1rocket2rocket3Englishman Pete Pearson believes that a Harley should be stripped down raw and yet be capable of being ridden hard all day, every day. No such a thing as “too beautiful to be ridden.” Although new on the custom scene – his shop Rocket Bobs Cycle Works was officially opened in 2009 – Pete is not a youngster, but a designer and engineer with a 30-year experience in the world of racing motorcycles. Whatever the trickiest parts he now creates for his bikes, more than anyone, he knows well in advance what will or will not work to be able to turn his creations into performance motorcycles

rocket4rocket5Pearson is obsessed with Harleys and only Harleys. Nothing is more important to him than to respect the style and design cues making them so unique. His inspiration draws heavily on Ratrods, Road and Drag racing bikes but must respect Harley-Davidson heritage. Mission accomplished with Gas’ d Rat, a “naked”, re designed, re-engineered and hand fabricated FXS powered by a 1979 Shovelhead motor.

rocket5bisDon’t be fooled by its apparent ultra simplicity. Gas d Rat features only precision custom components. Rocket Bobs Cycle Works is a small shop but is equipped with CMM Scanning, CAD CAM with 3 dedicated CNC mills, 3 CNC lathes, in-house suspension department which covers everything from basic lowering kits to full fork customizations, re-damping, shaving, etc. Well enough and more than necessary to produce anything Pete and his clients can dream up.

rocket6rocket7Three weeks ago, Pete Pearson was in Essen, Germany showing Gas’d Rat in the AMD World Championship Of Bike Building. His bike show competitors gave his custom creation high scores for performance components, finish and detail. Enough to rank it 3rd place in this tough world championship competition, rocketing Rocket Bobs Cycle Works has one of the best custom shops in the UK. Tech sheet below.

    Excellent!! A work of beauty!!!

    A “Harley should be stripped down raw and yet be capable of being ridden hard all day, every day” How do you do that with a bike that that seems to have never been started,let alone ever ridden?

    Holds just enough petrol to get him through the Chunnel!

  5. 5 Lorne Jun 3rd, 2013 at 8:25 am

    I really wanna see this motorcycle up close and in the flesh? I hear it will be making its UK debut at Beaulieu next week? Can’t wait. Well done not-so-young Pete!

  6. 6 Blue Jun 3rd, 2013 at 8:30 am

    Looking forward to a proper showcase at BSH Xtreme. Splendid work, Pete!

  7. 7 Lorne Jun 3rd, 2013 at 8:40 am

    Blue, Pete will have turned it into a bagger by then! 🙂

    “Pearson is obsessed with Harleys and only Harleys. Nothing is more important to him than to respect the style and design cues making them so unique.”

    Awesome build great attention to detail and a freestyle build that looks like you could ride it hard all day superb

  11. 11 po Jun 3rd, 2013 at 12:48 pm

    the details on this bike are insane. the they mount..the parts he fabricated and chose to run. the stack on the carb…mid controls…bars…fender…mono shock…u can stare at it for hours and find some new cool detail. cant wait to see what he comes out w next! congrats..well deserved

  12. 12 Jusmecuz Jun 3rd, 2013 at 2:12 pm

    I like everything from Rocket Bob’s, esp the custom parts he builds. He’s come out with some killer stuff for the later model Dynas. Great website too.

  13. 13 Pete Pearson Jun 3rd, 2013 at 2:47 pm

    Thanks very much for the props, it’s really appreciated, more than you guys will know 🙂 and major thanks to Cyril for running Gas’d Rat on his Blog, totally blown away 🙂

  14. 14 Iron Horse Jun 3rd, 2013 at 6:30 pm

    I like it a lot…unfortunately, at 6’5″ and 280lbs and with the placement of the controls, I’d look like Magilla Gorilla trying to ride it.

    I also really like the fusion of CNC quality parts and old school styling.

    Nice job Pete!

  15. 15 Mack Jun 4th, 2013 at 7:07 am

    Love it!!!

  16. 16 izadore007 Jun 4th, 2013 at 8:13 am

    Lovely to look at, Delightful to Hold, but if you could ride it, you would be Old. Cause there is no range to ride a Bike that hold 2 Liters of Petrol.

    I love the workmanship, especially those brakes. Hate the over the top claims. To me riding hard all day everyday is commuting 100 miles for work each way during the week, then taking a long weekend and putting 2000 miles on. On this bike that would mean 140 stops to refuel. Just not going to happen. The bike does impress me as craftsmanship that can really be ridden, unlike a lot of really cool but only for show bikes I see. It speaks for itself without the wild claims.

    great looking bike, superb blend of modern and caveman tech. Love it

  20. 20 D.P. Farley Jun 6th, 2013 at 3:52 am

    Looks like an “exercise in futility” to me, uncomfortable, and just a piece of expensive “Ass Candy”. It would never make the ride from NYC to Florida like many of my old Jap Bikes have done.

    Gotta love the haters.. 😉

  23. 23 Terence Tory Jun 6th, 2013 at 11:08 am

    Blue :”Gotta love the haters” Gotta admire guys who think bikes that have never even been started are “just dandy”.

  24. 24 Steve The Producer Johann Jun 6th, 2013 at 12:14 pm

    Thumbs up for the craftsmanship that is without a doubt.

    As for styling/ridability. I am not into the unfinished look and board for a seat thing. I prefer a more comfortable saddle and bigger tank for longer trips and more flow through image.

    But thats just me and my two cents.

    Always happy to see guys building from their point of view and not mine, otherwise life would be all about me and nothing else and that would be boring.

    Good on ya!

  25. 25 Pete Pearson Jun 6th, 2013 at 2:53 pm

    Don’t normally respond, you either get it or you don’t and that’s all cool with me. But the guy who states twice that my bike doesn’t run. Fist off in the AMD World Championships all bikes have to run and either submit a run video or run at the show,, not just run, but ride etc etc. The bike runs.

  26. 26 Motodavide Jun 7th, 2013 at 7:47 pm

    Yeah too bad his concept for a custom motorcycle to enter into the amd championship wasn’t an old jap bike with a giant cushion for clueless fat asses .throw in a giant windshield,huge gas tank,and a dashboard from a Hyundai with GPS and a stereo.dont forget those highway bars so you can layback and spread your legs like you do at the gynecologist.lastley offer plastic chrome covers so the skill less can truly customize their ride.dont worry the dealership will bolt it on for you. AMD builders are making mass production models right? Anyone can buy a bike and ride,,some can assemble,few can conceive then create their own one of a kind motorcycle dream. Pete you are one of the few,killer details man.the commenters will never get it.

  27. 27 Terence Tory Jun 7th, 2013 at 8:28 pm

    Motodavide,I look at the bike images and doubt it’s ever been started,and say so.The builder pipes up and says it’s been started,O.K. that’s fine.Then your head cracks open with a sulfphorous smell and outpours love and bile.I like your idea for a custom bike and it has potential,thanks.

  28. 28 Motodavide Jun 8th, 2013 at 2:03 pm

    Tory what do you see that says to you it doesn’t run? Or ever been started?
