It’s a heavy boxer week, with two BMWs from Europe and a flat tracker from the Siberian Urals. But first, let’s take a look at the new Crighton CR700W, with a rotary engine making well over 200 horsepower, and a Honda Hornet cafe racer from Brazil.

Crighton CR700W Rotary Motorcycle
CR700W In the UK, Crighton Motorcycles and Rotron Power just unveiled the new Crighton CR700W, and we’re in the process of passing out. Not because of its crisp lines, its Spondon-derived aluminum chassis, or its extensive carbon fiber properties. No, this one got us hooked because of its engine.

It is a 690cc fuel-injected rotary engine that produces a mind-blowing 220 horsepower. This makes it one of the most powerful naturally aspirated engines ever made, relative to its capacity, with more horsepower per liter than a MotoGP racing bike. And with a dry weight of 129.5 kilos [285 lbs], it has a power-to-weight ratio of 1.68 hp per kg.

As Asphalt & Rubber reports, the CR700W was designed at length and can trace its roots back to Norton’s racing program. A&R analyzed the numbers and described the CR700W as “Moto3 weights with SBK power numbers”.

Of course, the bicycle is rather expensive and very limited. Only 25 will be made, and each will be handcrafted by Brian Crighton at the company’s UK facilities. You need £ 85,000 plus tax [around $115,000] to get your name in the backlog.

You still get what you pay for. The CR700W’s engine is built in-house and paired with a custom Nova Transmissions box and innovative motorcycle-specific cooling systems. The specification also includes Dymag wheels, Öhlins or Bitubo suspensions and Brembo brakes. [Crighton Motorcycles]

Café racer Honda Hornet by Retrorides
Honda CB600F Hornet de Retrorides de Lourenço The Honda Hornet is not a common donor for custom projects, but done right, it has huge potential. This sharp Hornet-based café racer from the Brazilian Retrorides of Lourenço pleads in favor of Honda’s 97hp four-cylinder.

Retrorides is a family business run by José Lourenço and his sons Gustavo and Rodrigo. Rodrigo leaned into this project, because of his love and knowledge of Honda motorcycles. His idea here was to build a cafe racer with modern performance, but with design touches inspired by 1970s Honda.

“The first thing that bothered Rodrigo was the swingarm,” says Gustavo, “because the square design showed that the bike was from the 2000s. We built a jig to make a new one with the same geometry as the original, but with a new design.

The new trellis arrangement looks great and is complemented by the front forks of a Kawasaki Ninja ZX-6R. As the family machinist, Gustavo CNC machined a new set of aluminum triples, with a classic Honda “600 Four” pattern etched into the upper fork. Then he made a pair of aluminum hubs to attach a new set of hoops to.

Jose was responsible for designing a custom fuel tank, after the guys tried and gave up on the idea of ​​using a Honda CB750 tank on the bike. But the project fell through when he was hospitalized with heart problems and his doctor told him to put down the tools.

“We left the tank on the bench while waiting for it to return to the workshop,” says Gustavo. “Every time we looked at this tank on the bench, we missed him very much and feared his health, because we didn’t know what could happen to him.”

60 days later, Jose was fully recovered and back, finishing the tank with a CB750 gas cap to add a touch of elegance. The guys also made a new subframe, adding a solo seat and a little rear hump.

The rest of the parts list includes an Acewell speedometer, clips with new grips and handlebar mirrors, a Koso headlight and bespoke foot controls. There’s also a four-in-one exhaust system which improved the soundtrack and helped the Hornet lose more weight.

There are also a host of more subtle details, like the blacked-out radiator fluid reservoir and color coding on the gear batteries and rear shock spring. Wrapped in a delicious candy apple red finish with retro Honda graphics, this Hornet perfectly straddles the line between modern and classic. [Retrorides By Lourenço]

Basic restoration of the BMW R80 by Renard
BMW R80R by Renard Speed ​​Shop In 1997, long after its debut, BMW released a final version of the R80GS. Dubbed the “Basic” and finished in a simple white livery, it was a last chance for enthusiasts to own what was already shaping up to be a legendary machine. Now Estonian boutique Renard has built a beautiful homage to ‘Basic’, and we are in love with it.

Renard started with a BMW R80R from the 90s, then replaced the tank with an R80ST unit, which is almost identical to the old GS tank. They also modified the subframe to accept an ST seat tray, then fashioned their own seat to finish it off, with Alcantara padding.

From a distance, the white paint and vintage tank graphics make this bike look like an R80GS Basic. But Renard also worked on some neat details. The BMW wears a sleeker rear fender than the GS’s at the time, with a smaller taillight and thinner turn signals at both ends.

The side covers are in fact modified parts from Moto Guzzi and the exhaust is a reused BMW F800 part. In the cockpit are new handlebar risers and a Fuxxtech dashboard that combines the original clocks with a row of LED lights.

Look closely and you will also notice a slight sheen in the replica of the blue paint on the frame.

A carbon copy of the Basic would require a 21-inch front wheel, but Renard couldn’t find a replacement that would work with OEM brakes, so their version rides on the donor’s original 18F / 17R hoops. The suspension is also original, but not the engine; it is equipped with a 1000 cc kit from Siebenrock.

Like classic BMW restomods, this one is hard to beat. We would love to park it in the Bike EXIF ​​garage as a stylish daily rider. [Renard Speed Shop]

BMW R100RS customized by Cafe Racer Dreams
BMW R100RS by Cafe Racer Dreams Yes, Cafe Racer Dreams is still here (albeit with a new owner) and continues to produce BMW Boxers at assembly line speed. They’re in their 124th build now, and it’s a refreshing twist from the bobber style the Madrid boutique has become known for.

This BMW R100RS follows traditional cafe racer rules, but at a higher standard than most. The smooth black engine finish, blue frame and refreshing livery first catch your eye, but this BMW also packs respectable parts specs.

At the front is a Suzuki GSX-R1000 front end, with its Showa forks and two Tokico disc brakes. A set of Öhlins shock absorbers does its duty at the rear, connected to a brand new subframe. It even has responsive Dunlop Arrowmax tires.

At the top is a new half-fairing, mounted on a bespoke support system. Behind is a set of adjustable Tomaselli clips, flanking a CNC machined top yoke with an integrated Motogadget dashboard. Handles are “embossed” elements from Vans, and a set of Highsider mirrors conceal cleverly integrated LED turn signals.

CRD also installed Tarozzi footrests, custom fenders, and a pair of lowered GPR exhaust mufflers. Careful work by Spanish veterans. [Cafe Racer Dreams]

Ural IMZ M-72 flat tracker by Hammerbike
Ural IMZ M-72 by Hammerbike Customs The ancient customs of the Urals are a rare sight, but do you know what is rarer? A vintage Ural flat tracker, what is it.

This adorable quirk is based on a 1954 Ural IMZ M-72, and it’s the work of Roman Molchanov at Hammerbike Customs in Novosibirsk, Siberia. Roman has worked with the M-72 before, which is essentially a knockoff of the late 1930s BMW R71. But this time he had the itch of building a flat tracker with it.

“I like flat trackers and I also like flat head motors,” he tells us. “So I decided to put them together. “

The polished exterior of the Ural engine portends a redesign, but we were surprised at the extent of the work. Roman rebuilt it with forged pistons and modified cylinder heads, increased the compression ratio and made the flywheel lighter. It also has a racing camera and a new ignition, all mods which Roman says mimic Ural racing engines built in the 1950s.

Roman’s Ural also carries a surprising range of scalped parts, including Buell forks and Honda Comstar wheels. And despite its age, it sports a full line of stainless steel fasteners. Handcrafted touches include high exhausts and air filter.

Finished with a new seat, track bars, and a Harley-esque orange paint job, Roman’s Ural flat tracker is surprisingly attractive. He claims this is the world’s first M72 flat tracker, and he’s probably right, which is why this bike very cheekily carries the # 1 plates.
