Feel fee to add your story.

I bought mine after being off bikes since the 90's. Now in my 50's I Wasn't particularly after one but a 2005 38k miles mint example came my way and i never looked back. In my 3rd year of ownership and i have never had an ounce of trouble, its the bike thst does everything, tour, track, trounce and chill rides in one package and I only spent 3.8k euro on it, love it to bits.

It's the bike that got me back into bikeing but it's time for bike no. 2. Gonna go for an up to date naked 1 liter, its just a beast i need to slay but will be keeing the F4i. 45k miles on it now and the money I would be offered for it just wouldn't be worth selling for. I can see it staying with me until the very end. I met an old fella on an old tourer and he was in his 80's so perhaps that could be me one day. The F4i has the comfort and performance to do it.

In beautiful red, black and silver I still get more comments and complements on it when out in a group ride, even though my buddies have newer and better motorcycles. The modern classic that is the F4i is ideal as a keeper, mine now 21 years old still has plenty of life, add the fact that 20 year old and greater are pre euro cap rules and just have the rawness without the modern gizmos.

Here's to another 21 years :icon_beerchug: ]]> F4i - Main Forum Dicey https://cbrforum.com/forum/f4i-main-forum-11/why-i-will-never-sell-my-f4i-165312/
