Gr eat Britain 's S t e ve Saunde r s (Bet) edged fellow coun tryma n Rob Crawford (Bet) by one point (47-48) to win SiX-Riston brakes: Four is not enouglL W 2 hen Dutch chassis-bu ilder Nico Bakker fitted the first six-piston brake caliper (of hi s o wn manufacture) to his avant-garde, hub cente r-steering QCS roadster three years ago, it was dismissed as a marketing gimmick that was unlikely to catch o n. Four pi stons were quite eno ugh , said the cyn ics. Now , trends in the World Superb ike and Grand Prix Seri es are disproving that as J apanese giant Nissin ha s followed Sweden 's ISR along th e six piston route. But are there any rea l advantages? We p ut tha t qu estion to Yam aha Sweden rider And ers Andersson, who has developed the ISR brakes on h is factory-backed OWOI, leading perhaps to Yamaha 's own decision to be th e first to fit Nissin 's Swed ish ISR six -p iston brakes six-piston cali pers in the 1989 Suzuka 8-Hour. "T he improvement in braking performan ce is really fantast ic," answe red And ersson, " but it takes a circu it lik e J erez (Spa in) wh ere o ne hard-brakin g corner follows ano the r before you reall y understand th e tru e ben efit. I could brake with two fingers even late in the race wh en a four-piston brake would have started to go aw ay. But that 's not th e o nly reason . You can act ua lly save .5 kg. ( 1.1 Ibs.) unsprung weight by using the six -pi ston caliper, compared to a Nissin or a Brernbo , even using ISR' s 320mm cast-iron rotor. But becau se th e braking performance is so good, it's possible to save furth er weight by .reducin g the diamet~r of the brake disc, to at least 300mm and maybe 280mm. This also has the benefit of reducing gyroscopic effect and improving the steering, just like carbo n brakes, but wit ho ut their different feel and other problems like wet-weather use." Sounds like the braki ng equivalent of th e upside-down telescopic fork , in terms of prolonging th e effectiveness of an existing concept. What pads do th ey use? "At present we use six separa te machined-down Ferodo pads for th e small twin-piston rear Brembo, whi ch last for ages. I did th e whole practice and qua lifying at J erez, plus both races, on th e same set. But nowFerodo are making special pads for the calipers whi ch we'll have very sho rt ly." Made from lightweight aircraft a llo y of a type used in manufactu re of the Saab fighter plane, ISR boss Acke Rising 's products are grabbing th e Worl d Superbike scene fast! Alan Cathcart Honda reveals 1991 dual-PJITROSe bike A merican Hon da held a press conference and riding session recentl y to introduce its 1991 prototype XR250L dual-purpose motorcycle whi ch is designed to be "an XR with lights," according to Honda' s Jim Bates. The XR250L pro totype is po wered by a 249cc aircooled, fou r-stroke, single-cylinder engi ne, whic h is identical to the powerp lant of the strictly off-road XR250R excep t for mod ifications to meet U.S. federal noise and exhaus t emissions regul ati on s. The bike also XR250L is Hon da's answer to Suzuki DR250SL features a headli ght and taillight, . . . . blinkers, mirrors, steel gas tank , Pro-Link single-shock rear suspensio n and 41lll:m conventio nal front fork (both with 10.2 inches of wheel travel),.front and rear disc brakes, and a claimed dry weight of 253 pounds. The target pnce for the XR250L is $2998. Honda markets a similar du al-purpose motorcycle in Japan called. the.XL R250, but Bates says that the XR250L is not based on the XI.:R250, whi ch IS a more street-oriented d ual -purpose bike. However, some parts are m terchangea.ble. . The protot ype XR250L is now on its way back to Japan wher e It will soon be put into prod uction. the Scottish Six Days Trials, May 712. Wayne Braybrook (Bet), Steve Hole . (Bet) and J ohn La mpkin (Bet) ro unded ou t the to p five.

According to a report in the May 7 issue of the Orange County Business Journal , the financial mess which drove Malcolm Smith Inc. to file for Chapter I I recent ly - after parent com pa ny Transpac ific Holding Co. had earlier filed for Chapter 7 liquidation - is a complex one.
