Went from an FT500 thumper to a 1990 ZZR600 within a few months of getting my big bike licence. What a difference. I have owned the ZZR for over a year now and it has been so reliable, even through the winter. Strengths: Engine, power, comfort, reliability, very forgiving, easy to work on yourself. Weaknesses: Soft suspension, mushy brakes (braided hoses help alot)
I would recommend a ZZR to anyone as it will do anything, commuting, touring, a bit of scratching or a blast, it has the grin factor and the engine is bullet proof.
