I think your price is probably on the lean side...especially on a cruiser which has ALOT of chrome and an exposed engine and wiring/frame to polish by hand.
Japanese sport bikes are generally easier, as they are mostly plastic fairings, less nooks and crannys and very little chrome.
But overall, motorcyles are nothing BUT nooks and crannys and can take just as much, if not more time to properly detail than a car.
But when it comes to motorcycle detailing, don't sell yourself short. Detailing bikes takes different skills and precautions and some knowledge about motrcycles in general. Fortunately, I have owned 13 motorcycles and can draw from my past experiences.
If you use the wrong chemical in the wrong place on a car it just looks bad...do the same on a motorcycle and you can literally get someone killed.
The next time you detail a motorcycle ensure you point out a few things to your customer to justify your price:
-Let the customer know that you are not going to coat the tire tread with slippery tire gel so he wipes out the first time he leans over for a corner. Actually, let the customer know that you will not use ANY tire shine chemicals on his tires, since centrifugal force will eventually sling it onto the tread and be Veeeeery slippery and dangerous. Does your local wash rat know that?
-Let your customer know that you will THOROUGHLY buff in any protectant used on his seat, so it's not so dangerously slippery the first time he pops the clutch and peals out from a stop light and winds up catching his scrotum on the taillight as he hangs on for dear life. Same goes for the rubber hand grips, brake and clutch levers and rubberized footpegs. They should NOT be slippery.
-Let the customer know that you are not going to blast his exposed rubber wheel bearing seals with any high pressure (even from a normal garden hose on stream) since water can get past the rubber seal and into his wheel bearings. This can cause rust, squeak-squeak and potentially wheel lockup and wipe-out. Not good.
-Let the customer know that you are not going to spray harsh degreaser all over his expensive $160 sealed o-ring chain which will dry it out, quickly wear out the o-rings and wear the chain AND the sprokets prematurely. Degrease the wheel CAREFULLY, not the chain and sprokets-they're supposed to be greasy.
-Let the customer know that you must have extensive cleaning knowledge of the many different materials found on motorcycles vs cars. Many motorcycles have various parts made from painted steel, chrome, polished aluminum, carbon fiber, titanium, plastic, ABS Plastic, fiberglass, powdercoated parts, magnesium and others. Does your local wash rat know not to spray wheel cleaner or degreaser on those nice and shiny magnesium engine covers? I doubt it.
Point these differences out to people and charge for it. They'll see the value. Because of these reasons, I wont touch any motorcyle for less than $80.
Cutting your price doesn't always keep or get a customer. Doing excellent work and giving them their money's worth will. To encourage their business, instead of cutting your price consider "throwing in" an extra or two. perhaps a free bottle of air freshner, rain-x their windshield, give them a new microfiber towel for dusting, etc, etc. Once you cut that price, you can NEVER go up again no matter how many jobs you do for them.
