Well you could switch down to 4th gear. At 65 mph in 4th gear the engine runs at 8,000 rpm which is not redline but the bike does not like to do such high rpms for a long time. At least in 4th gear you could easily go 50-55 and not blow up the engine.

PS WW - sorry but your 27% is kind of, um, off - you add where you should multiply. Look at my earlier post how to calculate the percent change in gearing, just multiply the two increases: (18/15) x (41/38) = 1.29... which is 29..% more. Moot though.
