Former All Black wing Sitiveni Sivivatu ran in two of the tries as Les Jaunards stretched their home run to three-and-a-half years to equal the all-time French record held by Stade Francais.
French centre Wesley Fofana started the tour when he scored the first of the game's six tries in only the second minute. The home side were 25-3 to the good by the break and their only problem was the loss of skipper Aurelien Rougerie through injury after 15 minutes.
There were also 16 points from the boot of French scrum half Morgan Parra as Clermont moved to the top of the Top 14 with one game to play following a 26-25 defeat for leaders Toulon in Grenoble.
Meanwhile Clermont have confirmed the signings of scrum half Thierry Lacrampe and full back Mike Delany for next season.
They have captured New Zealander Delany from Japanese side Panasonic Wild Knights on an initial two-year deal while Castres half back Lacrampe joins the club on a three-year contract.
Clermont sporting director Jean-Marc Lhermet said the recruitment shows Clermont are aiming for stability and consistency.
"For several seasons we have built our workforce on a stable and solid frame," he said. "Our recruitment policy for next season is following this guideline and will be a sign of continuity with the arrival of two players, Mike Delany and Thierry Lacrampe. "
