Er-6f grips not coming off!
New here, just bought my first big bike (an Er-6f) after riding around on a 125 for 6 months, which I am LOVING! However, I've just bought some heated grips and went to fit them, and I cannot for the life of me undo the hex key on the side of the handlebars to remove the stock grips! I'm fairly certain it's not just me being weak (and I'm definitely turning lefty-loosey), to the extent where I've had a hex key drill bit on them, and been bashing the end of the hex key with a hammer, not lightly, and they just won't budge!
Don't get me wrong, I'm very happy that it's been built properly and is staying in one piece, but has anyone got any tips on how I might actually go about removing these?!
