‘It’s powered by a parallel twin with a 270-degree crank’ is such a commonplace now that riders probably do not pay attention to it anymore. However, they may notice the exhaust note sounds a little different than the ‘other’ parallel twins.

To understand this, let us go back a bit to another article about the CP4 a.k.a. crossplane engine. We spoke at length about the crankshaft and its crank pins (journals) where the big ends of the pistons’ connecting rods are mounted to.

In a traditional parallel-twin engine, the journals are spaced at 180° apart: When one piston is at the top of its stroke (called top dead centre, or TDC), the other is at the bottom of its stroke (called bottom dead centre, or BDC). In other words, one goes up, the other goes down.

Now, anything that has mass creates inertia, hence the primary force of one piston nearing the top is (nearly) balanced by the other piston nearing the bottom. However, these movements create a side-to-side motion called the ‘rocking couple’ which needs to be damped with counter rotating weights. Some riders do not like the lumpy exhaust note.

Certain manufacturers opt for the 360° crank to counter this, meaning both pistons rise and fall at the same time. Now you have no rocking couple, but the primary forces are X2. Several motorcycles actually used this format up until not long ago such as the old Triumph Bonnevilles (prior to the liquid-cooled version), the old BMW F 800 series. However, the 360° crank parallel-twin sounds like Boxer flat-twin.

So, here comes the 270° crank parallel-twin. Yamaha had debuted it in the 10-valve, 849cc, TRX850 in 1995/1996. Production of the bike stopped in 2011, but Yamaha believed in the engine layout’s potential, thus bringing it back as the CP2 (crossplane-2) in the MT-07 in 2014.

As hinted by the term, the crank journals are spaced 270° degrees apart. After one piston fires, the crankshaft rotates 270° before firing the other. No, the primary forces are not balanced, which is countered by the use of a balancer shaft.

The rocking couple still exists, but the effect is less pronounced due to the uneven firing order. The pistons are also always moving, unlike in a 360 or 180-degree twin, reducing inertia. However, the secondary forces in a 270° parallel twin are balanced.

This offset firing order gives the parallel twin a 90° V-twin-like exhaust note.

The true appeal of this engine format is packaging. In other words, it requires less space in a motorcycle’s frame, compared to a V-Twin as it the V-Twin is longer front-to-back. Also, the entire engine can be moved closer to the front wheel to promote better chassis balance at the front for better handling. A third advantage is that a more compact engine allows for a longer swingarm while maintaining a shorter overall wheelbase, again for quicker handling.

The list of bikes that use the 270° crank parallel-twin is long. Apart from the Yamaha MT-07, there are the Suzuki 800cc range, KTM 790 and 890 range, Triumph Bonneville, Honda X-ADV, Transalp 750, and Africa Twin, etc.

There are many materials used to make motorcycle clothing, a far cry from just leather many decades before, following the development of different types of motorcycles for different purposes. Let us look at Cordura.

Real world evaluation

This author had the opportunity to evaluate the RS Taichi RSJ330 Cordura Hoodie during this recent trip to Guangzhou, China. It is already in the middle of the winter months, as Beijing and Shanghai are already covered in snow. Guangzhou is situated much further south, so the weather was much more pleasant: 20° Celsius during the day, and as low as 12º Celsius at night. As such, it was not exactly the feature for full-blown winter gear.

The jacket held up truly well, keeping him warm for most of the day. As Cordura is breathable, it can get blustery and cold at night but an extra shirt underneath was all that it took.

So, what is Cordura?

Cordura was developed and trademarked by E.I. du Pont de Nemours and Company (DuPont) in 1929, Cordura is currently owned by Invista, a subsidiary of Koch Industries.

DuPont’s scientists were had tried to improve upon rayon, and came across Cordura as a “high-tenacity rayon, as strong as mild steel yet able to stand up under repeated flexing.” These two properties made Cordura suitable for a wide range of products including bags, shoes, clothing.

Cordura motorcycle gear refers to protective motorcycle clothing made from Cordura fabric, a high-quality nylon material known for its exceptional abrasion resistance, tear strength, and durability, making it a popular choice for motorcycle jackets, pants, and other riding gear, providing excellent protection against impacts and scrapes in case of a crash while offering a relatively lightweight and comfortable feel compared to traditional leather options.

Key points about Cordura motorcycle gear:
  • Abrasion resistance: The primary benefit of Cordura is its high resistance to abrasion, meaning it can withstand significant rubbing against rough surfaces like asphalt during a slide, minimizing skin damage in a crash.
  • Durability: Cordura is designed to last longer than many other fabrics, making it a good investment for riders who want long-lasting protective gear.
  • Flexibility: While strong, Cordura can be woven into fabrics with good flexibility, allowing for a comfortable range of motion while riding.
  • Weatherproofing: Cordura can be treated with waterproof coatings to protect against rain and wet weather, making it suitable for all riding conditions.
  • Variety of options: Cordura is used in a wide range of motorcycle gear, from lightweight summer jackets with mesh panels to heavier duty touring jackets with additional protective features.

Important considerations when choosing Cordura gear:
  • Denier rating: The “denier” number indicates the thickness of the Cordura fibers, with higher numbers signifying greater abrasion resistance. For example, 500D, 1000D and so forth.
  • Armor placement: Ensure the gear has proper armor placement at key impact areas like elbows, knees, and shoulders for optimal protection.
  • Ventilation: Check for mesh panels or other ventilation features for comfortable riding in hot weather. 

Yes, it is another Zontes but hear us out as there are so much to this bike! The Zontes 703RR represents the company’s first ever sojourn into the big capacity sportbike category, by utilising their new 699cc, three-cylinder, DOHC engine which also powers the 703F adventure model. It had just been launched at EICMA, less than a month prior to our visit.

The engine was in its design stages just five years ago. What we say back then there several renderings on a computer screen, and that was it. So take away two years due to the Covid-19 lockdowns, Zontes took only three years to make it happen.

What is the Zontes 703RR?

It is the sportbike of the Zontes family and looks to be the flagship model, at least in the time being. It features a beautifully sculpted and distinctive bodywork with sharp lines, even winglets covered in aerobodies.

A short highlight of its features include:

  • 699cc, inline-triple, DOHC engine, fed by a ram air intake. It produces 100.5hp at 11,200 RPM and 74.5Nm at 8,500 RPM. Ram air intake should add another 10hp in the upper RPMs.

  • The frame is real wow factor here: Each side of the twin-spar aluminium frame is cast as one piece then joined in with the other side. On the other hand ,conventional aluminium frames have their headstock and “uprights” that hold the swingarm pivot are welded onto the spars.

  • Zontes claims that this reduces the engine vibes and also provide better targeted stiffness vs. flex characteristics.
  • The subframe is also a one-piece cast aluminium component, and bolted to the back of the main frame.

  • Adjustable Marzocchi forks and monoshock.
  • Dual front disc brakes gripped by J.Juan calipers, dual-channel ABS is standard.

  • LED lighting all-around.
  • 8-inch colour TFT screen complete with power modes and lap timer.

  • 196kg wet weight.
  • Seat height is 795mm.
Riding the Zontes 703RR

If you like sportbikes, the seating position is so right. The ergonomics are somewhere along the lines of the Aprilia RS660 mixed with that of the Triumph Daytona 660. The clip-on handlebars are mounted slightly higher than the top of the fuel tank, so they do not put your weight onto your wrists. And that seat was so low that putting your feet down was of no issue.

The only place to test ride the bike was on a small test track at the factory’s compound. The front “straight” was just 100m long and there was a double-apex hairpin on each end, with a three-turn chicane in between. So it was tight like a small go-kart track.

Heading into the first turn, I squeezed the front brake lever with two fingers and was almost thrown out of the seat. It was THAT powerful!

Despite screwing up the corner entry from overbraking, the Zontes 703RR happily tipped into the corner without threatening to collapse the front tyre. Still in 2nd gear, I opened the throttle as the bike touched the apex and WHOOOOOOOOOP went the engine. Thankfully, the corners are marked by lines drawn on the road rather than curbs, because the bike shot all the way from the exit of the first corner to the last corner!

So, I short-shifted into 3rd and rounded the last turn, and stand the bike up quickly and rolled on the throttle to exit the corner. The 703RR just blasted down that 100m straight in a flash. The company’s CEO had insisted on building a three-cylinder engine because he prefers its strong torque and accessible horsepower.

I continued going around and around, and avoided making eye contact with those in the starting area because I did not want to be flagged in. In the end, a Zontes crew stepped almost onto the middle of the track to wave me in. I must have covered some 9 laps.

Conclusion

Yes, yes, it was a short ride but having ridden so many motorcycles before, I can confidently say that the Zontes 703RR has the chops of a great bike, although its prowess on the track needs to be discovered. But, as a midrange street superbike, the present contenders better watch their backs.

We asked Zontes Malaysia if it will make it here. The official returned a cheeky smile.

The Monster Energy Yamaha Team will drop VR46 Racing Apparel as their team apparel’s supplier beginning the 2025 MotoGP season. It is the end of a 4-year partnership.

Instead, Italian sportswear brand Macron will be the team’s official apparel partner. Macron will take on the role of sponsor and official supplier of team clothing, designing and producing official products and corporate uniforms, including racewear and travel gear. The company will also provide new uniforms for the Yamaha Motor Corporation and Yamaha Motor Racing.

This separation with VR46 Apparel adds to the list of Yamaha’s severance with Valentino Rossi’s various business projects. Previously, Yamaha also announced the termination of the Yamaha VR46 Master Camp, a young racer development program based at the VR46 Riders Academy facility for their Moto2 racing team.



As a step forward, Yamaha will rely on cooperation with its new satellite team, Pramac Racing, to develop young talent at pre-MotoGP level.

This decision also breaks rumors that the VR46 Racing Team will become a new Yamaha satellite team. On the other hand, VR46 chose to stay with Ducati, considering that the performance of Ducati motorbikes is much more competitive than Yamaha.

In fact, the relationship between VR46 and Ducati is increasingly close. Starting next season, VR46 will be the only Ducati satellite team that is supplied with the latest motorbikes, on par with the factory team. Full support will be given to Fabio Di Giannantonio, while Franco Morbidelli, a former Yamaha racer, will use a Ducati motorbike from this season.

Looks like the Chinese motorcycle makers know that sportbikes represent the pinnacle of engineering prowess, despite the ever growing popularity of adventure and sport-touring motorcycles. Just look around and you will see every Chinese motorcycle manufacturer having at least one sportbike in their line-up: Benelli, QJMotor, Kove, Zontes, and of course, CFMoto. Among them, the latter is the most aggressive, and has since filed the type approval for a CFMoto 750SR four-cylinder sportbike.

The new bike would probably be called the 750SR or 750SR-R (and 750SS in the US) has been filed as “CF750-2” in the type approval documents. Notice the “-2”? It could very well mean there will also be a naked 750NK variant.

What tips us off that this will be a four cylinder engine is due to the engine’s codename of “472MV.” Under Chinese type-approval conventions, the first digit – “4” in this case – alludes to the number of cylinders, while “72” here tells us about the engine’s bore size of 72mm. The CFMoto 675SR’s three-cylinder engine also has 72mm bores, so it may well mean the 750SR’s engine shares the smaller engine’s pistons, valves, and combuster chamber design.

CFMoto says that the 749cc engine produces a certified 110hp. Apart from that that, curb weight is listed at 213kg, and a maximum speed of 230km/h. Its ABS system is the Continental MK100. There is also a linkage to suggest a quickshifter.

That is all the information we have now. We are sure that it will not take long for the CFMoto 750SR to be launched.

 

 

The Bonneville Bobber became Triumph’s best-selling model when it was launched at the end of 2016. It has gone through several refreshers besides spawning the Triumph Factory Custom (TFC) model along the way. So, here is another Bobber TFC to usher in the new year, the 2025 Triumph Bobber TFC.

Of course, the TFC variant receives some high-end bling and components such as carbon fibre bodywork, two-tone gold black finish, retuned 1200cc engine, suspension, and electronics.

The engine’s mapping is more aggressive, moving the peak horsepower point down to 6,000 RPM from 7,000 RPM. Likewise, the peak torque of 106Nm was also moved to 3,750 RPM from 4,000 RPM. This is what is called a “cruiser” powerband – more tractable torque and power at lower RPMs. Capping off the performance shift, Triumph fitted a pair of Akrapovič silencers.

The 2025 Triumph Bobber TFC also receives Brembo M50 radially-mounted calipers, 310mm brake discs, and Brembo master cylinder. Up front are fully-adjustable Öhlins 43mm NIX 30 upside-down forks. The monoshock at the rear is adjustable for preload and rebound.

The standard Bobber has Road and Rain riding modes, so Triumph added a Sport mode for the TFC. The rear lights are integrated into the signal indicators. The front wheel is 19-inches and the standard handlebar is replaced with a clip-on type.

Apart from these, there are find hand-painted marble gold elements on the tank and side panels, with the underside of nine-litre fuel tank hand signed on the by the artist that painted it.

Other touches further include an embossed leather seat, carbon fibre mudguard stays, gold fork lowers, billet machined engine cover badges, and even a gold chain.

Price of the 2025 Triumph Bobber TFC in the UK is £17,195 (RM96,807.35) and it is limited to 750 units only.
