I went from a 1984 xt600 43f to an MT09 no probs they are great bikes with great power delivery just stay in B mode for a while and definitely in the wet. std mode is great fun and a rarely ride mine in Armageddon mode. just be gentle with the throttle I was a bit snappy with mine and pulled a wheelie in 4th gear A mode at 100mph totally took me by suprise( I dont do wheelies).
Best bike I have ever owned and mine is blazing orange, had the wheels powder coated (£60.00) same colour as the tank and it looks ace! put a GPR end can on (£219) tail tidy, rad guard and a stone chip kit on the forks and tank and one on the rear swing arm where the ABS rubs.
you've definitely got a cult bike on your hands.
All the best Bollins Enjoy!
