Yamaha YZF-R9 specifications
Yamaha · Supersport
Total Motorcycle says the R9 has a Deltabox gravity-cast frame that is the lightest aluminum frame ever offered on a Yamaha supersport, fully adjustable KYB suspension and nearly perfect 50/50 weight distribution, and that it keeps MotoGP-inspired styling while adding R1-level suspension and Brembo front brakes. The write-up says the bike is meant to build confidence in sport-minded riders from dedicated street riders to seasoned track-day pros.

CornerSpeed, a data site, computes a power-to-weight ratio of 0.272 hp per lb from the 119 PS claim and 430 lb wet weight, and says that for the price difference over the R7 you get 44 more horsepower, Brembo Stylema brakes and a complete IMU electronics package. Those are the site's calculations and comparisons, not a Yamaha statement.
Forum reaction
On the WERA forum thread one member says the R9 looks like an excellent candidate to replace an aging CBR600RR, as long as it comes in the lower-cost trim, and another plans little modification beyond an ECU flash and suspension.
Against the R7 and Panigale V2
The R9 costs $12,499 and the Panigale V2 is priced higher, while the R7 costs less. Yamaha lists a 32.7 in seat and 5.5 in of ground clearance. The choice is whether the extra 44 hp over the R7 and the electronics are worth the price.

The YZF-R9 is Yamaha's new middleweight supersport, built on the CP3 triple with an all-new aluminum frame, R1-level suspension and Brembo brakes. Bikenrider says it fills the R6-shaped hole in the lineup, and Yamaha asks $12,499.

The write-up says the bike is meant to build confidence in sport-minded riders from dedicated street riders to seasoned track-day pros.
Bikenrider rode it for a week on road and track and puts peak output at about 119 horsepower and 68 lb-ft, ahead of the old R6's top-end scream but with a different delivery. The report calls the bike a smarter, more versatile and more modern take on a middleweight supersport for riders who want genuine performance without giving up comfort and usability.
It notes what is missing: semi-active suspension, which the Ducati Panigale V2 offers at a higher price.

Against the R7 and Panigale V2.
The R9 costs $12,499 and the Panigale V2 is priced higher, while the R7 costs less. Yamaha lists a 32.7 in seat and 5.5 in of ground clearance. The choice is whether the extra 44 hp over the R7 and the electronics are worth the price.
Who it suits
The R9 suits a road rider who wants a modern supersport that will also survive a track day, without an R1's price, weight and edge. It is a better daily bike than a 600, according to Bikenrider, though the position is still a supersport's.

Yamaha's own R7 is the cheaper step down, and Ducati's Panigale V2 is the semi-active rival Bikenrider names.
