As I said above, love these TDR's. Their peak HP is about the same: TDR=46 HP (North America & OZ trim if my specs are right, maybe tuned to 50 HP in Japan?) Duke 390=44 HP. However, I believe the TDR makes its peak power up higher. I'm no two-stroke expert, so maybe you can tell us how the pipe is tuned?
Otherwise, very close to the same wet weight and suspension travel, although the TDR has a more relaxed steering geometry (27-degrees vs. 25 for the Duke) so it may be a little better on rougher roads. TDR has a wheel base almost one inch longer at 54.5" - the Duke is VERY short at 53.8". Fuel economy is probably a bit better on the 4-stroke Duke 390.
There were a whole bunch of bikes made between 1988 and 1993 that were way ahead of their time:
NT650 Hawk GT, CB-1 (CB400F or NC-27), GB-500 Clubman, VTR-250, TDR-250 (and parent TZR-250), RVF-400 (NC-35), FZR-400 Bandit, to name a very few in the small-to-mid-sized range. Perhaps we are entering another creative phase in smaller motorcycles. Maybe one of the very few benefits of a poor world economy?
