is 70 miles a day too much ?

[phillywilly]

just accepted a new job that is a 70 mile round trip per day and was thinking of using the fazer in the spring /summer to get there but because its only 600 cc i was thinking that it wouldnt be up to the job -even tho its only done 25 k and regularly serviced.
does anyone else commute on their bike this distance in the good weather ?- i know its only 70 miles per day but that would be 5 days per week (weather permitting )
perhaps we should have a sticky thread on here stating how many miles our bikes have done and if they are on first engines
