On last tire change service workers told me to use short straight, it lasts longer they say.
On my 2009 V-660 i had them on from 2010 and they were still fine when i sold the bike in 2014. On my FJR put them on in 2014 still working fine when i traded in the bike in 2016 in 2016 put them on my V-1000 still doing the job when i sold it late 2021...How long does angled stem live?
