I ride a motorcycle since 4 years and yes it definitely gets you attention. Especially from the calm and shy girls actually since it is an easy icebreaker and pushes their limit in a way they are often more willing to test than their sexual limits.
Also one ride can easily tell you whether she is into you or not.
You are close in a thrilling situation in which she will cling to you very close the more you angle in the curves.
You both have an excuse to be close in a physical manner and if their is a connection you can clearly feel that it is more than just holding on for dear live.
I personally find cruisers more appealing, but went for a semi sportsbike which can be ridden upright if you want but has that look to it for the attention it gets.
If you are socially retarded you can`t follow up and it at best will better your chances just slightly for a quick fuck. If you are not socially challenged however, this thing will be all you need.
