Video of the touching moment a British girl is surprised when she gets her first dirt bike as a surprise present.

The footage, captured on September 25 in Birmingham, shows 12-year-old Kayli Horton opening a gift box in which she finds a motorbike helmet.

Her father tells her to get changed so she runs to her bedroom where she finds a brand-new dirt bike.

Unable to control her excitement, she busts into tears.

''Kayli has watched her dad and brother on the motorcross track for quite some time now and was really interested and intrigued to get on the track herself,'' the mother later wrote online.

''She started off wanting to record her dad and brother on the track, which led to her wanting her own but (she) never thought (that) was possible.''

''We decided ... to surprise her with a bike and the full motorcross kit,'' she added.
