I would stay away from any 600CC SRAD. Those were pretty ass.
96 was the first year for the 750, 97 for the 600. they made teh 750’s till 2000 and the 600 till 01.
The 96 750 was the first mainstream FI sport bike and was an awesome machine. All teh 750’s were, the 600’s were pretty finicky and arse compared to the 750’s.
