My mindset is the smallest motor possible to do things because it pays off in handling. My 125 suffers a bit at high elevations but this thing never opens the powervalve so it just chugsThanks for the info, I appreciate it! Sounds like a fun machine! I dig the TX for sure but had a 250 with an RKTek head prior that has about the same grunt but felt lighter in the riding department. 4-9k is most common for me with an occasional 10k foray and that is my only concern and good to hear it handles it. I hear you on the kicker and it's looking like Beta might be the only option for one even though that's pricey as fuk. Have fun n'shit! Might have some riding in your zone questions this fall as I'll be passing through on my way to Pinecrest.
You should definitely try and get a ride in on one of the race editions if you think beta makes a bike you might want. Different worlds of suspension. The RRs are old man putt putt bikes.
Hit me up when pinecrest time. More mtb than moto in that area but lots of moto on the way there.
