Description:
Notes:
UMG Says: Heavy, awkward four that was a bit off the pace but lasted for reasonable mileages. Camchain and tensioner usually went first, followed by the valves and pistons. Mileages varied greatly, although few managed more than 75 thou and most were in trouble by 40k.
UBG Says: Heavy, awkward and bigger capacity custom version of XJ650 which lasted for reasonable mileages. Camchain and tensioner went first, followed by the valves and pistons. Shaft-drive eases maintenance. Over-complicated digital dashboard can cause problems. C1 £1000, C2 £700, C3 £350
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.
