PR Samurai motorcycle question.
 

I just got a "Mini Red Cycle" and a "Mini Green Cycle" on clearance at a drugstore. They're motorcycles (same mold just different colors) with a 3 3/4 Ranger figure. Decent for the 1.25 I paid,but nothing you need to track down.

Anyway,for anyone who has these,here's my question. Each one comes with two triangular pieces. Where do they go? The bikes look complete without them,and there's no instructions.

pics would help
