Looks like modding these bikes is a BIG waste of money, I really thought they would be at least a little more valuable after major modification. But I definitely made my mind up after reading how everyone says that these bikes are pretty worthless even after Major modification.
That's hardly an exclusive trait for the Vmax...mods to cars, trucks, sleds, bikes, quads, ect just don't pull their value at resale time. They just don't, never have and never will. The only possible exception I can think of is Jeep Wranglers, which can fetch stupid cash if modded up.
Think of it this way. Assume a totally stock Vmax is worth $5000. You add an aftermarket exhaust system that cost you $1000, an in the process obviously remove the original. At sale time, a prospective buyer expects a motorcycle to have an exhaust system and not shoot it straight out of the head. Therefore they're not willing to pay an extra $1000 for something they expect it to have. They might tolerate an extra $200 on the asking price if the system offers better performance but that's about it.
In my experience,
lightly modded bikes might fetch 10-20% of the value of the mods, on top of the bike's stock value. Stuff like chromed parts, different lights, LEDs, pegs, appearance stuff.
Big Ticket mods, like chain drive, radials, forks, motor work, ect, seem to fetch around 30-40% of their value back on top of stock value. That 1500 cost you $5k at a shop to build and tune? Your $5000 bike is now worth around $7000 if you were to turn around and sell it.
Nobody would care about the mod monkey if they knew all that cashola would find it's way back into their pocket eventually. Mods are for your personal enjoyment of the bike, and should be viewed as money
spent and gone. Joe Whoever that might end up with your bike probably doesn't have the same taste in directionals, or mirrors, or tail lights, and even if he did wouldn't pay you retail price for them since they're now
used and expected.
Keep all the stock parts, and while it pains people to do it, if you sell your bike, put it as back to stock as is realistic. Things like exhausts, carb setups, wheels, ect are worth much more as parts than as additional value on a bike. You can probably sell that $1000 rear wheel to someone for $600 and double your amount returned.
