EXTENSIVE MODIFICATIONS “ The motor features extensive modification of all areas of the design . It involved modification or replacement of crankcases , custom made pistons , cylinder , valves , custom made connecting rods , cylinder head , clutch , gearbox , exhaust , carburettors , and induction system . “ Unlike the big Suzuki 1100s , where you can buy nearly everything off the shelf , there is very little aftermarket supply of performance parts for the Yamaha Genesis motors . Given that fact , why not go with the Suzuki 1100-based solution ? After all , any FZR-based bike would be giving away 250cc of displacement against the bigbored Suzukis of up to 1300cc . “ The higher RPM capability of the FZR motor would make up for some of that handicap , but the better of those Suzukis make upwards of over 100lbft of torque . It would take a lot of smart effort to overcome that sort of displacement handicap . The answer lies in the total package integrated solution that the Yamaha Genesis bikes provided . The FZR motors are relatively compact for the era , certainly for a motor that features the traditional horizontal disposition of the gearbox shafts . This allows a tighter package with the motor relatively forward in the chassis compared to the Suzuki .
“ Overall it ’ s a much more compact engine in height , length , and width . The better bias of weight allows a more compact , easier turning chassis . This was true in the FZR1000 , and it was further evident in the compact nature of the OW-01 , which was produced in limited numbers as a World Superbike homologation special . That model was freed of the constraints of road bike expectations like comfort and passenger accommodation . The original FZ750 and early FZR1000 had the motor ’ s cylinders lying at a 45-degree angle . In 1989 the new FZR1000 ( and OW-01 ) featured a 35-degree angle . This was done to enable a more compact chassis , shortening the wheelbase . “ The race bike chassis features an unmodified OW-01 frame mated to a modified FZR1000 swingarm . This job was very well done by Marty Lyall . The front forks are standard OW-01 with internal modifications done by Kerry at KTEC . The rear suspension is an original equipment Öhlins , again internally modified by Kerry . The front brakes are Brembo calipers from a 1989 Ducati 851 . The triple clamp assembly is an after-market copy of the original YEC race kit geometry . They feature a shallower offset , and stronger upper and lower yokes .
