I´m ready to upgrade to a liter bike, and have my selection narrowed down to the Speed Triple or a ZRX1200R. I need some input from Speed Triple owners to help me make the right choice. Some reviews infer that its a twitchy-steering, uncontrollable wheelie monster. I should add that I´m 6´4" and 250lbs. I sure would appreciate any help, as I am leaning towards the Triumph.
