Yup, lots of fun roads out there with good scenery.Heading west from Katy you can take racer road 359 & 1458 out of Brookshire. Note that the LEOS know that 1458 is called racer road too, so no racing. From that area find 1094 in Sealy and head to New Ulm and the Frelsburg twisties on 1291. Then into Fayetteville for lunch at Orsaks or Joes. Pivo's Ice House in Lone Oak is supposed to have good burgers, but I can't vouch for it. Yankee's Tavern in Roans Prairie is popular with the biker crowd and has decent food considering it's a bar. 3090 between Brenham and 244 is pretty interesting. I don't know the area well, but if I were leaving from NW Harris county I'd just ride north and west on the FMs as they suited my fancy and I found the place. There can be some bicycle traffic out there, but there are some good roads around Magnolia.
No super technical stuff, I'm on a V-Strom 650...but got skid, plate and Shinkos so as ready as a Strom can be...so dirt and gravel mostlyYup, lots of fun roads out there with good scenery.
I do a loop going south from Brooksire on 1489 to Simonton, then west on 1093, north 1458 all the way to Pattison. North on FM 359 to a little road called Adams Flat over to Wilson road. This brings me to 529 and I go home from there.
As said, there are a few roads south of New Ulm (Bostik, New Mintz/Weishuhn) that are fun.
FM 949 east of Cat Springs is also a fun little road.
I also found a nice road south of Hempstead/west of Bellville called FM 331. Nothing spectacular scenery wise, but has a few very high speed curves on it, good road conditions and little traffic.
Now you don't mention if your looking for street or offroad/dual sport. All this above is street.
