gilera 125 dna 2002?

at the right side of the front wheel as u sit on the bike that is where the speedo cable runs too,perhaps this may need to be checked out.try to figure out if its the bike speedo cable and components or the digital display which needs sorting.if the tyres have been changed recently the cable may not hav been fitted back to the front tyre properly or it has came loose.try removing the front tyre and checking the cable components and re-fitting properly.hope this is of some help to u
