motorcycle mixup

Situation: Your best friend wants to get a motorcycle so badly and has waited for three years to finally get one. His neighbor is selling his motorcycle and your friend has the money to buy it. Here's the part that really gets to you...one of your uncles died riding one, your aunt just got into an accident and is suffering in the hospital, another uncle lost two limbs and a friend of yours now has a metal rod running through his shin; all because of motorcycle accidents. You really don't think its a good idea that he gets a motorcycle of his own. You are too worried about his safety after all you've been through. Do you tell him not to get the bike of his dreams and make him possible angry with you or really sad or let him get the bike and have that constant worry in the pit of your stomach? Do you reason with him and tell him about all those family horror stories in hope that he will chicken out? You dont want to ruin a friendship over a silly bike, what do you do?
