Its funny you mention it being turbine smooth. That was a description I used when I got mine. 4th gear from 10mph all the way up to silly speed. Like a turbine, not a hint of snatching or coughing.
Or even 6th at 30mph and pin it....is a Gen1 Thou pretty similar? Going to have the CBF as my 365 commuter and thinking now about changing the 600 for one of the Gen1's up for sale to have as a weekender (or give the 600 some needed TLC). The Tiger I just can't part with - not many around and it gets lots of comments.
Out of curiosity BB, mine's a 57 bike and just running my first tankful to check range so what are you getting to a tank ?
Same riding style as my other bikes and currently have 136 miles clocked up with a tad over a 1/4 tank left (I know it's 4 litres left at top of red mark)
