Overview[edit | edit source]
uzuki GSX-R 400R-SPII
The GSX-R400
got a new frame (GK73A) and new overall appearance in 1988. The new model was
presented in February 1988. The redesigned GSX-R got once again new fairing and
shorter wheelbase, but the weight increased a bit due to the stronger new
chassis and exhaust system. The model also got slingshot carburetors, polished
chrome silencers, curved radiator, Tokico 4-cylinder front brake calipers and a
rear hugger mudguard.
The new 4
into 2 exhaust was meant to increase the torque on the mid-range band, but had
only a marginal effect.
The 400cc
series were increasing popularity in Japan and a production racer with different
suspension and gearing, GSX-R400 SP (Sports Production) was presented for 1988.
It looked almost identical with the standard GSX-R400 but didn't have passenger
foot pegs and you could spot the rear suspension gas reservoir peeking out from
under the seat. Also the front suspension was different from the standard model.
The SP version also had a Sports Production logo on the tailpiece.
To compete in
production racing, the manufacturers produce SP (Sports Production) versions of
their sports bikes. These usually have fully adjustable suspension, close ratio
gearboxes and a single seat but didn't have more power, due to Japanese
motorcycle manufacturer's power restriction code.
The SP's are
claimed to be even harder work on the road than a standard GSX-R400. Not that
surprising knowing that it was designed for racing only.
Available
colors: Blue/White, Black/Red/White, Black
The SP model was available in Blue/White only.
