VOL. 51 ISSUE 15 APRIL 15, 2014 P73 So what's changed from the previous mod- el? Let's start with the 1199cc parallel twin that powers the Super Tenere. In an effort to change the character of the powerplant a bit, Yamaha made some changes to the shape of the intake and exhaust ports – straightening the exhaust port and changing the exhaust port shape from a D shape to round. The changes are designed to increase gas flow efficiency and to make the twin spin up quicker while also increasing power output. Additionally, in an ef- fort to reduce friction, the Super Tenere gets new piston rings, the piston skirt curve shape has been changed, and the exhaust cam jour- nal width has been reduced. The exhaust system has also been revised with the connector between the two pipes get- ting eliminated – again to try and improve the power characteristics. The only other change to the engine is changing the clutch damper from a spring type to a rubber type. Yamaha says this is to reduce mechanical noise and vi- bration – i.e. get rid of the clunking sensation from the clutch. The chassis on the bike is totally unchanged. It remains a stressed member –designed to keep the powerplant as low in the stiff chassis as possible. On the suspension side of things, the only change is that Yamaha has changed the inner cylinder piston rod of its fully adjustable 43mm KYB fork from steel to aluminum in order to save weight. The quick-adjust (tool free with a nice big knob) rear shock remains as it was, offering up 7.5 inches of travel. The other changes are mainly for rider com- fort. For starters, the windscreen gets a new shape that's an inch and a half wider and half an inch taller. It's also got better adjustability – four positions/2.3 inches – that doesn't re- The ES version of the Super Tenere gets a KYB electronically controlled suspension package and heated grips.
