We were stunned by Cedric Smith’s Gold Wing based CBR1800RR when we saw it back on The Kneeslider back in September. Now, we finally have some quality images.

The bike was built from a totaled 2010 Honda Gold Wing with a CBR subframe added to it, a GSX-R front end and CBR Repsol fairings.

Cedric Smith, the creator of this motorcycle, is a service technician at Everett Powersports in Washington state. He’s also customized a Honda RS125GP racer to accept a CRF450 engine and used a TL1000 engine to build a custom flat tracker.

The CBR1800RR is currently sitting in the Everett Powersports showroom and you can check it out for yourself. It reportedly rides like a CBR sportbike, yet its bit smoother with that longer wheelbase.

Those claims aren’t totally without merit either. Like the CBR1000RR, the Gold Wing is equipped with a “Pro-Link” linkage monoshock and is, even in stock 904lbs form, capable of a surprising turn of speed down a twisty road. Here fitted with steeper front suspension angles, better brakes and more ground clearance, we bet this thing is actually surprisingly good.

    I bet the little Honda project is an absolute missile! An RS125 only weighs about 150lbs (dry) with the stock engine, so you can imagine what happens when you shoehorn a 450cc dirtbike engine in.

  • Kr Tong

    THose bikes looks insane. I have no idea what they’d be like in real life and i really want to find out.

  • The_Doctor

    Oh, that TL Tracker is goddamn awesome. Would hoon.

  • Lawrences

    It comes “standard” with the squiddly swinging arm :)

  • Echelon

    I’m a repsol owner/lover myself… but this just hurts.

  • Jordan

    I think it makes for a better looking bike than a stock Hayabusa or ZX-14, honestly.

    • Damo Von Maciel

      Agreed. Not missing the ghost flames.

    moar info on the RSF450 build and ride plz


    It’s a POS motor. Definitely not designed for high performance. could have done better with 2 1000cc motors, would weigh less, and go faster.

    • Ricardo Gozinya

      It’s certainly not a sportbike motor, but I don’t know where you get that it’s a POS. If the builder were looking for outright speed and performance, they wouldn’t have built this to begin with. But if you’re looking for an engine with superior power to weight ratios, why bother with 1000cc motors? Those things are pretty weak compared to the kind of power output you can get from a Wankel. The NRV588 puts out 170 hp, and weighs in at 285 lbs for the whole bike. And that’s with a chassis identical to what most superbikes use.

      Clearly, by your own guidelines, 1000cc inline 4s are all POS motors.


        The Goldwing motor is a V-6. today’s 1000cc inline-4 motors put out 200hp, 2 of those weigh less than 1 goldwing motor, which is at least a 10 year old design (pre-historic in technological terms)

        • Ricardo Gozinya

          Actually the Goldwing engine is a flat six (Originally a flat four, back when it was called the GL1000), and the design is quite a bit older than 10 years, even if you only count the 1800, it’s 13 years old. Also, it was built, from the get go, as an engine for a touring bike, not a race bike.

          As for this specific bike, according to the builder, it’s not a CBR with a GW engine, it’s a Goldwing that’s had a huge weight reduction.

          • NIGHTSCOUT

            Then what was the point of wrapping the engine in sportbike parts? Stupid…..

            • Ricardo Gozinya

              I’m guessing it had something to do with fun, as well as the challenge of doing it. While it’s not something that fits my personal tastes, I really don’t see anything to be negative about. It’s a well thought out, well executed custom motorcycle. I’m sure it’s also a ton of fun to ride.

              • NIGHTSCOUT

                The geometry feel must be worse than a harley.


        Also, rotary motors have reliability issues. They are not used for a reason.

        • Ricardo Gozinya

          Yes, but they’re better at making power, and weigh less. Which were your criteria.
