Yamaha FZ8 2011 The FZ8’s

The FZ8’s twin front disc brake specs are nearly identical, at 310mm front when compared to 320mm discs for that FZ1. Just one 267mm disc at the spine contrasts having a 245mm rear disc about the FZ1. Both of them are pinched by similar four-piston front, and single-piston rear calipers.Both ride on the similar 43mm inverted fork along with a link-type Monocross rear shock, sharing a 57.5-inch wheelbase. The FZ8’s suspension can be adjusted just for rear preload.

  


 




How it Works
 
2011 Yamaha FZ8 Review


Depending on whether you’re feeling like a glass-half-full or half-empty kind of person, you could either say the FZ8 feels like a 600 – but with power like a strong 750 – or you could say it’s like a detuned, lighter FZ1.
But while the FZ8’s 12.0:1 compression, fuel-injected engine shares the FZ1’s crankcase, 53.6mm stroke and basic architecture, it is not accurate to call it a sleeved-down version of the 11.5:1 compression FZ1 mill.
To begin with, the FZ8’s four-valve-per cylinder head is all new, as are its shorter lift and duration camshafts, and new intake funnels – 125mm-long for cylinders 1 and 4, and 150mm-long for cylinders 2 and 3 – that help broaden its powerband.
Coupled with its 35mm throttle body – 10mm narrower than the FZ1’s – these features enhance torque while still allowing for a respectable top-end rush.
Yamaha doesn’t make power claims, but the FZ8’s 11,500-max-rpm mill reportedly peaks at around 105 hp, and 61 ft-lb torque when measured at the crankshaft.
Speaking of which, the crankshaft is modeled on the FZ1’s but weighs 30% less, which Yamaha says helps it still rev quickly, while positively influencing handling.

 
Straddling one is also meant to be as unintimidating as possible. Coupled with an identical 32.1-inch seat height, Yamaha says it narrowed the rear of the 4.5 gallon fuel tank and the front of the rider’s saddle just to help shorter riders reach the ground.
