Dirt Bike Grips Will These Parts Fit On This Dirt Bike?

Will these parts fit on this Dirt Bike? - dirt bike grips

My family has an old 1985 Honda CRF 250R Dirt Bike is in good shape, and I wonder, packaging, plastic part in it because the plastic is completely exhausted and we need new plastics. All suggestions are welcome. Also, we need new drivers, because they old pieces of scrap metal. All proposals will be accepted for good.
