I have an 01 R1 and have been riding it daily for a few years. Everybody has an opinion on certain bikes like they do with cars. Test ride a few, see which one feels the best.
At the moment $22 fills the r1 and gets me just over 200ks. $78 in the GTR gets me shy of 300.
Rego is cheaper and the r1 in standard trim is much faster than my 34 gtr v spec.
Sux to ride in the rain but just go easy and harden up a little. Have to be very careful for other drivers though.
On a good dry day, i enjoy riding the bike more than driving the GTR. Putting your knee down on a corner is an awesome buzz.
