Suzuki SV650?

Question

I was riding my bike today, Everything seemed fine, I was on the motorway and selected the gear's fine, But after a while it would only go into 1st and 2nd gear luckly i was on local roads at the time but It wouldn't let me select 3rd or higher,

Any idea's what it could be?

Answer 1

Clutch needs adjustment or the engine oil is low/ extremely dirty, check the latter first.

Answer 2

What Chris said.. Change your engine oil and filter
