60 or 70 profile front tyre
60 or 70 profile front tyre
Just noticed my front tyre is 120/17 / 60, should be 70 profile, havent noticed any real difference when riding , is this small difference noticeable on normal commuting riding ?
Re: 60 or 70 profile front tyre
Should definitely be a 120/70x17.
The 60 will have a slightly lower profile. 60% of 120 instead of 70%.
I'd stick with a 70, but if you're not having any issues, it can probably wait until you next change it.
Only issue I can think is if you ever had an incident and an insurance assessor noticed it wasn't the right size.

120/60's make for better turn in but a harsher ride due to the shorter sidewall. This can result in a push, chatter during braking or mid-corner chatter. Some bikes and setups are more affected than others. F2's will push the front when ridden hard with a 120/60.
When ridden hard, the 120/70 is the better, more compliant tire. However, many riders will hardly notice the difference until they really start using the front. 120/60’s tend to be cheaper than 120/70’s so unless you or your bike are sensitive to the use of a 120/60, it can be a good alternative especially for someone just starting out, or just having fun.
