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
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.
