Honda to build limited edition Honda CB1100 RS 5Four

The Honda CB1100 RS 5Four is being specially built by Guy Willison and is to commemorate the factory endurance racing motorcycles of the 70s and 80s

Honda CB1100 RS 5Four

HONDA UK has teamed up with 5Four Motorcycles to build 54 versions of  Honda's CB1100 RS 5Four. The creation of the machine also coincides with the 50th anniversary year of Honda’s iconic CB750, widely regarded as the first true superbike.

To facilitate the build of the bike, Honda has joined forces with Guy Willison as seen on the Motorcycle Show and owner of 5Four motorcycles. Willison will start with a base CB100 RS, creating the machine you see here with the addition of, a works endurance racer paint scheme, Racefit 4-2 exhaust system, low set looking Renthal bars, Tomaselli grips and slimline mirrors.

To keep the machine as authentic as possible, Willison has shunned the usual plastic mouldings of a modern bike in favour of hand-crafted aluminium panels for the headlight shroud and seat unit. Finishing off the latter with a hand-stitched Alcantara leather seat.

To order one of these limited-run machines, prospective owners should first call their local Honda dealer with a deposit to secure their machine. Honda will then confirm an estimated delivery date with the dealer as well as the number of the bike. With the hand-built machines being built to order, it’s this likely to be around three months before owners can begin collecting their machines.

Honda CB1100 RS 5Four price

The list price for 5Four is £15,554 which, while a fair chunk more than the standard machine, does make it possibly the best value numbered, limited-edition motorcycle currently available – and probably a very shrewd investment for the future.

When the bike is ready the new owner can either collect it from their dealer or arrange to collect the 5Four from 5Four motorcycles Corby base. If the latter is chosen, the bike will be handed over personally by Guy. Potential buyers can also opt to finance their exclusive new machine with a PCP deal or a personal loan.

Who is Guy Willison?

Guy Willison is the creative force behind 5Four motorcycles, the Corby based custom shop specialising in one-off versions of production motorcycles like the CB1100 RS. Guy started out as a dispatch rider, later becoming an engine tuner and now a builder. Willison recently found fame on TV’s The Motorcycle Show, working alongside long-time host Henry Cole. Speaking about the new Honda he said:

“5Four Motorcycles was created to move away from the one-size-fits-all standard and to build thoroughbred machines with cool design, a statement of individualism, quality, performance and exclusivity. From the moment I first saw the CB1100 RS I knew it had the potential to be a thoroughbred, single seat, point-and-squirt A and B road blaster. So, we’re making a strictly limited production run of 54 CB1100 RS 5Four motorcycles, each individually numbered. The number is etched subtly into the number 5 of the nickel plated 5Four badge which itself is inset into the tailpiece. And the paintwork had to hark back to the period in my youth when Honda dominated World Endurance Racing with their Red, White and Blue Works racers; there are no stickers or transfers – even the retro Honda logo and Wing are lovingly hand-painted. We’re passionate about this motorcycle. We have just selfishly designed and built it and it stirs us when we walk up to it and we don’t want to leave it at the end of a day’s riding.” And why 5Four? Simple: “That was my despatch call number…”
