For anyone interested here's a short amateur comparison of the two bikes.... The first thing that hits you in the face when looking at the RSV4 is the compact size of it, more like a 600 supersport than a 180bhp superbike, the second thing is its ride height when you climb onboard, its quite a bit taller in the saddle than the long and low 999 and also squatter and more dense, where the 999 has a waisted midriff the RSV is fuller, but although I am roughly 5'10'' and 13.5 stone it doesn't really feel cramped . Starting is different as well, you need to keep a finger on the starter until it catches unlike the one touch 999,and when it does start the noise is loud (Akrapovic system),and not dissimilar to the 999 but with a more fulsome and addictive raspy edge to it. Pulling away and 1st gear engages with a clunk ,the cable clutch feels quite light and gear selection is positive, although finding neutral at a standstill is not as easy as it should be,also in the cockpit display there is a useful gear indicator, which I sorely missed on my old 999 ,constantly trying to shift up a further gear when already in top. Out on the open road it really feels nice ,with 3 power modes, R for road ,S for sport and T for track,i haven't had the time to venture beyond R yet ,which limits the bike to 140 bhp, with S bringing the umph up to 160 break and T being full power at a claimed 180bhp...to be quite frank R feels plenty for me until I recalibrate and get to know the bike properly ,but I have a feeling the power available In T will be way beyond my humble capabilities! Being the Factory model the bike is equipped with Ohlins suspenders all round as on the 999S,the wheels are forged alloy, and unsurprisingly it handles very well with the forks soaking up almost everything our shite UK roads have to offer, all in all its a very pretty bike and an accomplished package ,I was tempted to go for one of the later APRC models, but launch/traction control,and wheelie control bollox isn't really my thing and I wanted to keep things as pure as possible. Anyway...time to take our cat to the vet, gotta go.
