The Yamaha Diversion series of motorcycles are all-round touring motorcycles, and descent from Yamaha's earlier XJ series. All Diversion models are fitted with a four-stroke air-cooled 8-valve inline-four engine.
The Yamaha Diversion series consists of three models: the XJ600S, the XJ600N, and the XJ900S.
The XJ600S Diversion/Seca II
The XJ600S is known as the Diversion in most parts of the world, and as Seca II in the US market. The bike has a small top fairing, although a lower fairing is available as an accessory. The XJ600S is a descendant of the earlier Yamaha XJ600 model that were manufactured 1984-1991. The bike is fitted with a 598cc, air-cooled 8-valve inline-four engine giving 61HP / 55Nm output. The engine was tuned from the original XJ600 model towards improved low- and midrange power, sacrificing some of the peak power in the process.
The Diversion/Seca II models were manufactured in 1992-2003. As the Diversion/Seca II design is based on an earlier well-matured bike model, changes made to the bike during these years were rather subtle, mostly concerning improvements in fairing, a second front brake disc and small oil cooler appearing in 1996 model plus improvements in carburetors.
The bike is considered to be an affordable entry-level bike that can give plenty of fun for its price.
The XJ600N is almost identical to the XJ600S, except that it is a naked bike.
The XJ900S is known as Diversion 900 on the European market, but was never sold in the Americas. The XJ900S is a descendant of the earlier Yamaha XJ900 model. The bike is fitted with a 892cc, air-cooled 8-valve inline-four engine giving 89HP / 85Nm output. The Diversion 900 bike is a highly affordable sports/touring machine with more than enough power to make it a sensible commuter machine but also great fun to ride on less mundane journeys. Like the XJ600S, the XJ900S has a small top fairing.
