Road tax for bikes over 600cc rises from £66 to £70 from April 1. The 6% rise was contained in yesterday’s Budget.
Tax for bikes between 401cc and 600cc rises from £48 to £50 while the rate for smaller bikes remains frozen at £15 for up to 150cc and £33 for up to 400cc.
The Motorcycle Action Group said tax should have been frozen for bikes which comply with the latest European emission limits, known as Euro 4.
A spokesman said: “We believe that because there are now Euro 4 compliant machines available, the Government should have done for bikes what it’s done for cars and at least frozen the level for those motorcycles.
“We also think the Government should have extended the scrappage scheme that was made available for cars to bikes.”
