Actually they'd probably say "we don't know sir". The bike is a Triumph.
What we have is fully, and totally, uneducated responses without any experience to make such judgements. Just remember that...
I stand corrected. I just called two TRIUMPH dealers and asked what size tire goes on the rear of this bike. They both said 180!
I guess in my 30 years of riding, I am still uneducated and have no experience, just like these dumb shop owners. Whatever dude.
Look, you can stick a bunch of different sprockets on a bike as well. So, according to your outlook, if someone takes a bike in that came with a 17 tooth front sprocket and a 190 rear tire, there is nothing "wrong" with giving the customer their bike back with a 170 tire and a 15 tooth sprocket right? Because some buddy of yours at the track has tried it and it worked.
Sure, whatever guy. You seem to think that your opinion is
fact and everyone elses' is just an opinion. Truth is, it is still just an
opinion.
Will the bike work with a 160? Sure. Obviously. I've tried a 160, 170, and 180 on my bike. They all "worked". However, if I dropped it off with a 180 PP on it and told the guy "please replace the rear tire" I would expect it back with the same size. How is this "uneducated" and "inexperienced"?
No need to name call and get all angry. Just a reasonable response other than "some guys have used all kinds of different tire sizes and it's fine" and maybe you'll change my mind...
