The
Yamaha R1 series first began in 1987 with the FZR1000, Yamaha introduced several motorcycle
engineering firsts including the boxed aluminum "DeltaBox" frame,
advanced intake and exhausts technologies including a 5
valve-per-cylinder head and an exhaust EXUP power-valve. The engines
usable power output was dramatically improved throughout the entire
RPM range and featured one of the flattest power curves ever seen on a
motorcycle. The aluminum Deltabox frame was very light and rigid when
compared to steel and both handling and braking were vastly improved
over the old-style steel cradle frames. These numerous advances made
the FZR1000 a veritable "tour de force" and it was voted "bike of the
decade" by many who found it to be quite capable both on and off the
track.
For the next four years Yamaha enjoyed significant sales and racing
success, however in 1992 Honda introduced the CBR900RR Fireblade which
was essentially a marriage of the chassis used for their 600cc
motorcycles with an over-bored 750cc engine. Even though the
Fireblades weren't as powerful as the FZR1000, it was lighter and
shorter which resulted in much quicker handling. It took Yamaha four
years to realize the significant weight and power changes that were
introduced in the short-lived YZF1000R "ThunderAce". Still, the
YZF1000R was based on the original Genesis engine which was canted
forward sharply causing the wheelbase to be longer than the Fireblades So before
you buy that new exhaust or if you're looking for another upgrade.
