DPS officials say it happened about 5:40 Monday as 45-year-old Thomas Reid Murphy was heading westbound on FM 367 on his 2006 Suzuki Motorcycle.
A DPS spokesman says Murphy failed to make the curve in the road, ran off the road to the right, and struck a fence.
Officials say he was taken to the hospital but died from his injuries.
And they say he was not wearing a helmet.
No other vehicles were involved.
