    Not much that I can give to you. Just publish a custom motorcycle and there are no targets, at least once a week. At this time, it would be a great honor for me! It’s absolutely perfect and this is very special. Because, this bike is already sent by someone who led a large forum that I highly respect.

    The owner of this bike is René Tollkühn. He is the admin of the largest cafe racer forum in Germany. When most people build a motorcycle to win the trophy in a custom show. Not the case with René, he build a beautiful bike is not only to be a window-dressing. He did it solely through his own effort and then to be ridden by himself.

    What inspired you to start building the bike? I love the classic racing bikes from Honda, but I wanted to pursue my own ideas. True to the motto “Less is more”, a phrase from the Robert Browning poem “Andrea del Sarto, also called ‘The Faultless Painter’” published in 1855.

    Where did it come from? I bought the bike from an older man. It was at the time no longer in their original condition. The plan is “Minimalism” and had a clean cockpit. The concept: only black color (frames, tires, rubber parts), bare metal and brown leather. That would make it look perfect.

    What did you do to the bike? The firts process, rear frame section has been cut to obtain the desired length, then proceed with painting. As already mentioned above the concept is only black color, the previous frame color is green. And then, do the same with Rico Pardeyke, start ordering aluminum tank, seat, side covers, fenders and chain guard to Friedhelm Lammers. I let him to do the job because he’s the best.

    Then the wheels, get a used bike is a job that requires extra time, and even can be said to build from scratch is complicated. What I do in this section is renewed spokes and polish it. Not only that, some small aluminum parts were polished. For an example, as you can see on the clutch cover of the engine.

    For the braking part, which is not yet visible in the photo. Major changes were made on the rear brake. René said he had installed a product from Classic Tube, it’s StopFlex® stainless steel braided hoses and according to some opinions it will increase of braking performance by doing away with the soft spongy brake pedal.

    On the front brakes have done some adjustments. For the rear brake if you pay attention to this part, the rotor has been drilled. Why did you do that? I think it was quite successful to get the right settings were adjusted to StopFlex to get the best braking performance.

    For this CB750 Four F1, the chassis has been optimized, and eccentric bearing has been repaired. For the swingarm, it using KONI shock absorbers for Honda Bol d’Or. For the front forks, it using progressive fork springs that designed for touring motorcycles that need the adjustability for varying load capacities.

    I do the installation for an instrument that will make the cockpit had a classic look. It is a Motogadget Chrono Classic Instrument. Top yoke ordered from Dime City Cycles. The outside part of cockpit made shiny, this is the perfect touch combined with clip-on handlebars. You know, it’s a Cafe Racer.

    Some changes also have been made on the electrical part. It is an attempt to return it into normal “engine can run as is”. The main thing, LiFePO4 battery has been installed. Engine has been revised and the displacement has increased to 836cc using Wiseco piston kit.

    Some of the standard features that can be found here, but it’s still interesting. Use of Mikuni flat slide carburetor TMR-fitted with K&N air filter and the usual things that are still popular is the use of polished open line 4-into-1 exhaust system. This makes the bike more sparkle and make you feel good-looking when you ride this bike.

    The final result for ’76 Honda CB750 Four F1 Cafe Racer Project, this bike has been stripped-down 36 kg originate mainly from the upper part of the machine and thus the entire focus has shifted noticeably down. It rides really great. It is very handy and the conclusion is I’m very happy after rebuild this bike.
    Why I decided for a CB750 Four? Primarily because the motor characteristic, the appearance and frame geometry. She also has the incomparable sound of the classic Honda racing machines of the 60s and 70s lasting impression and infected. It is raw, pure and genuine. I love it and want to enjoy it.
    If you have any questions about this bike. Please add René Tollkühn as your friend and chat with him.
