Gers, who tackle Kilmarnock in their SPL opener this weekend, gave virtually the whole of their squad a chance to impress manager Walter Smith.
No less than 19 players turned out for the Light Blues, including exciting prospect Jamie Ness in midfield.
One negative for Rangers was the loss of teenager John Fleck, who had to be stretchered off after damaging his hamstring.
Gers' bright start was rewarded with their opening goal on eight minutes when Naismith slid home beyond John Hutchison from Kenny's neat pass.
Their second arrived on 24 minutes when Kenny capitalised on some poor defending before firing past Hutchison with a good finish.
Clyde finished the half in the ascendancy and just a few minutes into the second half they pulled a goal back through John Stewart.
Smith gave a host of youngsters the chance to shine late on and while they failed to build on their lead the friendly proved a worthwhile exercise.
