Hi NetRiders, Well its close to upgrade time again and ive been itching for a bigger 600cc - 1000cc bike, something with more torque and more go, something that wont need shifting twice to do one corner and something with engine braking for a more relaxed ride..............basically a more relaxed type of bike. At the moment im looking at a D675 and a Yamaha R1, both very beautiful beasts. First question is how difficult would it be to go from an RS 125 to a bigger bike like a D675 and an R1? who has done this or similar jumps and do you have any advice to give? Ive tried bigger bikes before but never threw it around in anger and certainly not at a track..............something about crashing another mans bike doesnt appeal to me (or crashing for that matter). If a bigger bike isnt advisable then id most likely stick with the lovely two stroke, most likely an RS250. I love the two stroke smell, sound and feel, but just hate all the shifting, the small sweet spot, and being as chicane to bigger bikes. How much are lowering kits for R1's and D675 and do they have allot of padding to shave off? Im not a tall dude by any sense of the word so height is very important to me. The R1 im looking at is a 2006 50th Anniversary bike.............the yellow and black. Do this bike come with a slipper clutch? and apart from colour, is this bike exactly the same as all other 2006 R1s?
