Motorcycles, part 3.

Here’s another model for the MSRP of off-road motorcycles.

a) Would this be a good model to use to predict the price of an off-road motorcycle if you knew its bore, clearance, and engine strokes? Explain.

b) The Suzuki DR650SE had an MSRP of $4999 and a 4-stroke engine, with a bore of 100 inches. Can you use this model to estimate its Clearance? Explain.
