Compared to the previous Yamaha R1, the ’09 model is sharper steering but still retains the familiar Yamaha neutral feel. The R1’s twin-spar deltabox frame and swingarm, made up of die-cast and pressed sheets of aluminium has the balance and dimensions similar to the factory M1. It’s now stronger and weaker in all the right areas, like more flex in steering head area for better front end feel and more rigidity in swingarm pivot for control.
The engine is mounted 9° steeper and 8.2mm further forward than before, putting more weight on the front end. Weight distribution is now 52.4%, 47.6% front to rear. The riding position is more compact (bars are 10mm closer to rider, the seat 7.6mm further forward and pegs 10mm forward). The wheelbase is down 5mm to 1415mm.
An R6-type magnesium subframe, shorter titanium end cans and a shorter, lower fuel tank improve mass-centralisation. Footrests are now two-way adjustable, 155mm up and 3mm back.
43mm upside down forks now have independent damping, compression in left, rebound in right leg. Yamaha says this improves the damping response. As the forks are connected by the yokes and wheel spindle it’s all one unit, so is still balanced out properly. The rear shock has a new bottom link set-up and a new hydraulic preload adjuster. The steering damper is now speed sensitive, controlled electronically
The ’09 Yamaha R1 carries the same six-piston caliper (but on different design carriers) and 310mm disc set-up as the previous model Discs are slightly lighter than before. The master cylinder lever ratio is improved and lightened by 25g and the lever shape itself is new. The rear tyre profile is up from 50 to 55-section for better side grip.
