Bridgestone launched its premium Battlax Hyper Sport S20 tyre with a major press test event at the Portimão circuit in Portugal, 14th to 20th March 2012. More than 100 journalists from the European and international motorcycle press attended a presentation of the new Hyper Sport tyre. They then tested it for themselves in groups on the challenging 4.7 kilometer Autódromo Internacional do Algarve circuit, which hosts the FIM Superbike World Championship and FIA Formula One testing. On the second day, journalists took a road tour on the S20 around the Algarve. Later in the week, Bridgestone invited customers from across Europe to a similar presentation and test drive at Portimão.
“We wanted the press to feel the MotoGP genes in the new Battlax S20” says Vincent Van Houtte, Manager Motorcycle Tyre Products, Bridgestone Europe.
Designed with Bridgestone MotoGP technology
Using the “S” (= Sport) symbol for the first time on a Battlax tyre, the premium S20 completes Bridgestone’s Hyper Sport product line-up that includes the Battlax BT-016 PRO and BT-016 amongst other sport specialists for road and track.
The development target for the S20 was to meet the demands of European sport riders of high-powered machines from 600 to 1300cc for the highest handling performance in dry and wet on all types of roads and riding conditions: highway touring, winding country roads, city streets and track circuits. Bridgestone engineers turned to their MotoGP experience for the answers.
“Test results of the new S20 show that Bridgestone can take MotoGP technology and apply it to a road tyre. To date, the S20 is the closest production tyre to MotoGP and thus benefits more than any other from Bridgestone’s MotoGP successes” says Vincent Van Houtte, Manager Motorcycle Tyre Products, Bridgestone Europe.
Larger contact area at all angles
Compared to the BT-016 PRO the S20 has superior handling on wet and dry, while maintaining excellent wear life performance. Bridgestone’s proven construction with Mono-Spiral Belt (MSB) and High Tensile Super Penetrated Cord (HTSPC) has been optimized to produce a larger ground contact patch at all riding angles, providing more grip in all conditions. At lower camber angles, this larger contact area improves the contact feel and adds ride comfort; at medium and higher angles, riders enjoy more cornering stability.
The S20 tread pattern is designed with grooves that straighten out in the centre of the tread, improving cornering performance when the angle is low, particularly at turn-in. On the front, the side grooves run up to the shoulder, providing better contact feels at high angles and stronger grip on wet and dry. On the rear, the wider grooves give confident grip in the wet.
"The S20’s large contact area and grip level come from its MotoGP genes. Sporty riders can tackle the angles with full confidence” says Dominique Plom, Assistant Manager, Field Engineer, Bridgestone Europe.
The new compound with Silica Rich and Bridgestone’s proprietary NanoPro-TechTM polymer, which reduces heat build-up during tyre rotation, provides improved grip in the wet and at low temperatures. This also gives confident grip right from the start during warm-up, without sacrificing mileage performance on front or rear.
The triple-layer compound (3LC) with an optimized segmentation of soft and harder compound has been applied on front and rear, improving dry grip as well as giving high stability in cornering and good mileage.
New wet grip benchmark
Test results versus Bridgestone’s BT-016 PRO tyre show that the new S20 delivers improved grip on dry roads, giving more confidence for cornering, and high-level sporty handling. On the track, riders can expect high cornering stability and faster lap times through better and more balanced grip on front and rear.
Bridgestone tests show that the S20 wet grip is even better than the BT-016 PRO already the established standard in the wet. Results also show the high stability that comes from improved grip, with easy control in heavy rain conditions.
This high-level grip has been achieved without sacrificing mileage performance. Bridgestone tests confirm that the new S20 compound has excellent wear resistance, providing high mileage on front and rear tyres.
