Could anyone let me know if you can use the abby sky lift on a gtr1400 or can it be modified to accept one or is there an alternative lift ,
I'm not sure about the ABBA system I'd drop them an email. However depending on your budget take a look at Pro Bike Lifts, they do a very decent cross section of bike lifts to suit various budgets.
Personally I wouldn't entertain any modified lift for any bike particularly one as heavy as a GTR1400.
A lift of any type is one of those things that after you purchase one then you wonder how you ever managed without one
