Tfhe 650 came out in '05 with a 5th gear, overdrive. Does the 400 have overdrive?
Just to be clear, though: the 650's tranny is also "Continuously Variable" unless in Manual mode.docta said:...The 400 uses a continuously variable transmission, ie., a conventional variator. The 650 uses a very sophisticated control system to actuate an electric motor that selects preset ratios in both the normal and power modes. It also allows overdrive to be selected via electronic actuation.
The only way that would be possible would be to increase the size of the drive and driven pulleys as well as the length of the belt. As you can see in this picture the entire transmission housing would have to be made bigger to accommodate the larger pulleys. The transmission housing is cast as part of the engine case, so overdrive on the 400 won't happen until Suzuki decides to do it.docta said:It may be possible that one of the aftermarket variators can be had with higher (numerically lower) final ratio, while still retaining the low-end ratio.
