The police slow-down campaign focuses on urging bikers to think of the consequences a crash could have - including the impact on their family.
Superintendent Iain Murray, Head of Road Policing at Police Scotland, said: "Most serious and fatal motorcycle collisions happen in rural areas involving higher speed limits.
"So our message is clear. When you're out on your bike over the summer make sure you make it back to your loved ones.
"Roll off the throttle -don't risk it for their sake."
As the motorcycle season gets under way this weekend, police are warning middle-aged male bikers to take particular care when out on the roads. Motorbikes represent 1% of road traffic but account for 12% of fatalities
Police said nine in 10 biker casualties are men, with nearly one-third of those casualties in their 40s.
Transport Minister Keith Brown said: "There is no room for complacency and we need to continue to analyse what is going on and address any emerging issues which the data presents."
More than 85% of all motorcycle incidents happen during the biking season, between April and September.
Superintendent Murray added: "Throughout this campaign, we want to encourage safer, considerate biking behaviour among riders, particularly during the summer months.
"With statistics unfortunately showing most motorcycle casualties occur during the day and in good weather, and with more motorcyclists getting their bikes out at the start of summer, it's important to take it easy in all conditions."
