as said my cousin races R1's and he's about 6'6 but alot bigger built that you lewis, and he looks very odd on the bike, also he found it very difficult to get his knee down for a while and when you that tall you give the bike a much higher centre of gravity, and it fells very unerving.

That aside before he got his race bike he had a CBR Blade 99RR and that bike was alot lot bigger than the r1 and that that suit his size wise much better.

So maybe a CRB 400FI or CBR 600F ?
