Ryker 600 - will the speed/RPM be too high for a regular 75mph commute?

[BLUEKNIGHT911]

My Brother and his wife are thinking about buying Ryker 600's, they both are retired from the USAF. He is 70 and she is 60 years old. He said it's not about speed for them they just want to enjoy riding together on their on Ryker's. Both have never owned two wheelers so they feel it would be easy to learn to ride an automatic three wheeler.

Many, many folks here who have never been on a MTC prior had much better " learning " experiences .... because they were never on a Mtc. ..... good for them .... Mike
