Motorcyclists from Legana and Bridgewater will face court after they were allegedly caught speeding on the weekend, with one of the men accused of doing more than double the legal limit.
Both men held learner driver licences and were not meant to travel more than 80km/h.
According to police, the 30-year-old Bridgewater man was travelling at 129km/h on the Midland Highway near Campbell Town at 5.35pm Saturday. The blue Kawasaki motorcycle he was riding was seized by police.

At 8pm police conducting mobile speed checks allegedly busted the 18-year-old Legana man travelling at 157km/h on the West Tamar Highway near Legana. The black Kawasaki he was riding was returned to its registered owner.
Tasmania Police Detective Inspector Craig Fox said the men will be charged with hooning offences and appear in court at a later date.
"This type of behaviour is the perfect set of circumstances where serious crashes occur - speed and inexperience," Detective Fox said.
"Especially after the fatal crash of a motorcyclist in Launceston last weekend, police can't believe the stupidity of these riders who have learnt nothing."
Detective Fox said police increased efforts to catch people whose decision to speed could kill.
"Unfortunately speeding, hooning and high-risk driving behaviours are a constant concern for Tasmania Police and this is reflected in our priorities," he said.
"I wouldn't say that there has been an increase in those types of behaviours but the simple fact that those with highest level of inexperience - learner licence holders - are doing such high speeds, shows their disregard for their own safety and of others.
"There has been an increase in our presence on mobile radar detection duties, due to speeding being a major contributor to fatal crashes."
Marked and unmarked vehicles were being used to target hot spots, country roads and urban areas, Detective Fox said.
