changing from 200cc dual-sport?
In South Africa, I have a 2004 Honda CTX200B(ushlander), an agricultural bike (dual sport). Top speed standard was about 100 kmph (60mph) on flats, but I changed sprockets, adding a tooth in front and dropping two in back. Now I’m up to about 110 on flats, 100 going up hills (sometimes as low as 90...), and 120+ going down hills. So, the question: am I going to kill this engine by riding it this way for 3 years/34,000 km (20,000 miles)? I’m wide open about half the time—the rest I’m on dirt or curves or slower speed limits.
(FYI, I’d like to keep this bike, since my wife rides, too, and likes it, and I already have it. The bike market here is weird—everything holds value for a long time. I’d like a slightly bigger dual-sport, even up to the 650s, but prices are too high here. This was US$2500 barely broken in, and a good condition KLR with 15,000 miles is $4200. I’d like something with a bigger tank—this one is only 8.5L/2.2gal.—in addition to higher speeds. Or I could go for a 250 road bike, standard style, to get slightly higher speeds, though I like how tough this machine is…Sigh.)
