Brembo Stylema 108mm Caliper

Brembo Stylema 108mm Caliper

Features:

• Piston diameter 30mm (4pots of the same diameter)
• Mounting Pitch 108mm

Note, when upgrading from stock calipers, consideration of ABS and Master Cylinder may be required.

THE ADVANTAGES OF THE STYLEMA​​

The Stylema uses pistons with a 30 mm (1.18 in) diameter, for an even greater weight reduction compared with the previous caliper.

The reduced amount of brake fluid in the hydraulic circuit, together with the rigidity of the caliper body, means a shorter lever stroke and hence better braking control, which in turn means greater safety.

All this in a caliper body that’s 9% lighter, with lower stud bolts and shorter fastening screws, and not forgetting that even the ventilation is better on the Stylema, thanks to the wider air transit areas around the pistons and the opening in the central bridge that helps the air to flow out.

The proof of this lies in the 10% temperature reduction in the brake fluid, clearly helping it not to reach boiling point. This means preventing vapour lock, where the formation of vapour makes the lever spongy, with a negative effect on braking efficiency. ​​​

SUZUKI HAYABUSA: THE LEGEND IS REJUVENATED WITH THE BREMBO STYLEMA 108 CALIPER

Suzuki Hayabusa, the first bike in the world to use the Stylema 108 mm model.

Compared with the Brembo M4 32 caliper used on the second generation Hayabusa, produced from 2013 on, there’s been a huge leap forward: the Stylema stands out through its compact and lightweight design, boosted ventilation and more sculptural form, and in terms of performance it’s unbeatable for hard braking.​

When it appeared in 1999, the Suzuki Hayabusa was in turn the fastest road-going motorbike in the world. Its peak speed of 312 km/h (194 mph) was reached thanks to a 1.299 cc straight-4 engine, but also its perfectly aerodynamic profile that cut air resistance down to a minimum. Strangely enough, it was precisely that year, in the World Championship premier 500cc class, that Suzuki bikes were the first to use the radial mounted calipers conceived and made by Brembo. A seemingly impossible solution on the face of it, given also the difficulty of integrating them with the forks used up until then in competitions.

At that time, Brembo’s radial mounted calipers had a centre distance of 108 mm (4.25 in) because that was considered the best for ensuring rigidity and solidity.

It was thanks also to these calipers that, in 1999, Kenny Roberts Jr won 4 GP races on his Suzuki RGV and ended the 500 class championship in second place. Also in 2000 he won 4 GP that combined with other 5 podiums allowed him to clinch his first world title, two races before the end of the season.

Over the years, Brembo’s radial mounted calipers became standard parts on the track from 500-MotoGP down, for anyone who wanted great braking sensitivity and unmatched performance.

The switch from track to mass production for road-going motorbikes was but a short step. The Brembo engineers opted for a smaller caliper so the center distance was also reduced to 100 mm (3.9 in), and this has since become the standard measurement for the radial calipers of European road bikes. In Japan on the other hand, the urge to maintain that tie between supersport bikes for road use and those for competitions led to keeping the 108 centre distance, which has therefore become the fixed reference for nearly all the Japanese sports versions.

That’s why, when Brembo launched the Stylema caliper at the end of 2017, it made it with a 100 mm centre distance for European manufacturers but then developed a separate 108 version specifically for the Suzuki Hayabusa, the first bike in the world to use the Stylema 108 mm model. And despite happening this way purely by chance, it does seem like the two companies have come full circle since 1999 when one launched the first Hayabusa and the other the first radial caliper.
