What's wrong?
The oil plug and dipstick on the 2010 Triumph Sprint GT and Sprint ST motorcycles is the part the owner removes to check engine oil level. The dipstick is supposed to reach the correct depth in the oil reservoir so the mark on the stick matches the amount of oil in the engine.
On affected motorcycles, the plug and dipstick is the wrong length. That means the reading on the dipstick does not reliably show whether the engine has enough oil. A rider who checks the oil can believe the level is adequate when it is not, leaving the engine to run with less oil than Triumph intended.
There is no warning sign before failure. The problem is in the measuring part itself, so the normal oil check does not give the owner a dependable early clue.
Who's affected?
The scope is limited to the Sprint GT and Sprint ST, with the same engine and engine cooling component category for both.

A matching 2010 Triumph Sprint model does not guarantee inclusion. Check your VIN to confirm whether your specific motorcycle is included.
What's the safety risk?
Low engine oil can cause the engine to seize, which can lead to loss of vehicle control and increase crash risk. If your VIN is included, schedule the recall repair soon and ask the dealer what to do if the motorcycle cannot be moved safely. Repair will be free at any franchised Triumph dealer once available.
What should I do?
- Check your VIN to confirm your 2010 Triumph Sprint GT or Sprint ST is included in this recall.
- Confirm whether Triumph mailed the December 24, 2010 owner notice for your motorcycle, or call Triumph customer service at 678-539-8782 for recall instructions.
- Contact a franchised Triumph dealer and ask whether the free engine oil plug/dipstick replacement is open for your VIN.
- Reference recall number 10V639 when you call so the dealer can match the repair to the oil-level dipstick defect.
- Keep engine oil at the correct level until the repair is complete.
What happens at the repair
At the dealer, a Triumph technician replaces the engine oil plug/dipstick fitted to the clutch cover. The replacement corrects the dipstick length so the oil level reading matches the amount of oil in the engine. Parts and labor are covered under the recall. If your VIN is included, ask the service desk to confirm the recall work before the motorcycle is released.
