UMG Says: Shaft drive four which lacks build quality and has some clutch, gearbox and valve problems after the first 30,000 miles. Lack of power between 4-6000rpm’s normal. As are rotten exhausts, poor brakes and leaking head gaskets. Metz’s are good tyres. Rare turbo version shifts okay but heavy and complex (as in expensive to replace) engine. Anything with more than 50 thou on the clock’s going to be lots of trouble, with chronic electrics, starting and engine hassles.
IGM Says (XJ550 Seca, XJ550 Maxim, XJ650 Seca, XJ650 Maxim, XJ700 Maxim): Yamaha’s first four-cylinder mid-sized engine series, which powers all these bikes, set new standards for performance when introduced in 1981 and has proven rugged and dependable over the years. The same basic engine design is still used in the 1998 Seca II.
