    Heavily modified engine, Ohlins suspension, Brembo brakes -- the GT650RS has it all

    Heavily modified engine, Ohlins suspension, Brembo brakes -- the GT650RS has it all

    Having teamed up with Royal Enfield, South Korean custom house CrazyGarage has come up with an insanely modified Royal Enfield Continental GT 650, called the GT650RS. In the video, Kim Chi-hyun, founder of the custom house, says he was inspired by the AMA Superbike races (for naked bikes) from the 1980s for this build. With this motorcycle, Kim intends to participate in the Retro Race Trophy time trial event at the Korea International Circuit this year. Drool over the exhaust note and other details in this short video:

    Coming back to the motorcycle, Kim has modified the engine heavily with parts from S&S Cycle. We’re talking about high-compression pistons increasing the ratio from 9.5:1 to 11:1, aftermarket cam and clutch, and a Dynojet Power Commander ECU tuned to match the custom race-spec exhaust system. The 6-speed transmission is enhanced by a Dynojet quickshifter and a quick throttle fitted onto the lowered, clip-on handlebars. To ensure better thermal efficiency, the oil cooler has been repositioned to the headlight area, with a small offset halogen headlamp sitting atop. 

    To go with all that extra firepower, Kim has used a custom 43mm Ohlins inverted front fork and an Ohlins TTX rear monoshock, both adjustable. The stock brakes have been replaced with fiercer Brembo twin discs (with axial calipers), aftermarket brake lines, and a pair of custom carbon-fibre air ducts up front for enhanced cooling. There’s no ABS as it is a track-focused machine. 

    Completing the setup are the single-sided swingarm borrowed from the ’90s’ Honda VFR400R and a pair of 17-inch lightweight alloy wheels from Marchesini, wrapped in Metzeler Racetec RR rubber for optimum grip. Other additions include a lightweight lithium-ion battery, an aftermarket tachometer with an LCD temperature gauge, and dedicated switchgear for changing the ignition mapping.

    Another interesting aspect of this custom build is the bespoke fuel tank. Kim says making this was one of the most memorable parts of the process. He fabricated a custom 9-litre fuel tank and mounted it below the seat for better weight distribution. He then made another custom tank (likely for cosmetic purposes) where the original one was located. 

    This is by far one of the most purposeful, extreme builds we’ve ever seen based on the Continental GT 650. We hope the motorcycle helps Kim perform outstandingly at the time trial event!

      Pro and cons of gt650
      Its good bike only if you can handle it because of its weigth and high cc, its not beginner friendly but if you have experience with high cc and heavy bike its gonna be best bike for its price. but its still not good for day to day or city driving because of its heating and low mileage, its gonna be a problem.

      Good and bad
      I wanted good classy looking cool bike and GT 650 is exactly what I wanted, it has no competitor. If given second chance of choosing bike, I would still pick this up instead of speedy KTM bikes. Only problem it has is the weight is hard to manage and it can be hard to turn in corners but I knew what I was buying. Its a good bike, I have some burn marks on my legs but that is what I expect it gets hot and you can feel the heat in city but it won't shut down and cause issue, you should treat it like a 600 cc bike and properly respect its weight in corners and city. Only if you have other bikes and cars. This being your primary day to day bike is not can be easy to use in a city or day to day commute to office. It will be too much of power and weight. Only buy for highways and sunday ride.

      Its a whole different vibe with 650
      That bulky boy and speed makes the bike very attractive and muscular and it gives the vibe that other bike can't give you if you'er going to college or office the royal enfild continental gt 650 would be the best option. Eventually its good for mileage and comfort for short rides if you have the capacity for riding on full throttle then you will get deficiencies for mileage, if we ride like a gentleman then we can feel the comfort and safety. If you can maintain the bike and do proper maintenance it would be a great option to choose because this bike has its own aura and there is no similar bike like royal enfiled gt 650 in the market for a middle call this bike is best.

      ​Performance on Terrain man! the bike handles "even on uneven roads" and has a "strong pickup" compared to others in its class. ​Costs maintenance is minimal and specifically bought it for "fuel saving" to avoid recurring petrol costs. ​ the gear shifts as "soft" and the engine as remaining "smooth" even after a year of riding ~40 km daily. ​ Recommend for both beginners and daily office commuters.
