[QUOTE="Constant Mesh, post: 269550, member: 615"] Baloney! The engineers don't have any excuses for not offering a smoother engine. Both bikes have the same engine configuration -- in-line 4. If it turns out that the Concours engine is noticeably smoother then obviously Yamaha's engineers dropped the ball. They had an opportunity with a clean sheet design to do it right. The twin balancer design is a proven, established technology for in-line 4 engines. Particularly for a touring machine where a multi-hour ride is not uncommon any unnecessary vibration causes additional rider fatigue. Did they just tack on the balancer shafts so they could say they were offering a smooth engine? My 33K mile '04 FJR I bought from D&H has been a good, reliable machine. But I've always wondered why they didn't do a better job of eliminating engine vibration. The technology was available to make a very smooth engine. Their execution of the technology just wasn't spot on. [/QUOTE]
