Stumbled across this pre moto3 bike online. Looks pretty cool and a lot cheaper than the MD250’s. Thought I’d share and see if anyone here has anymore info on it.

I just missed out on buying used MD250H for $6k last month! :eek:

I think both bikes are heads above Ninja 250 for race bike, being purposely designed as race-bike from beginning. Meaning frame is not overbuilt and super-heavy meant for 2 people. Bike design starts with frame and there's absolutely nothing you can do once that design is carved in stone.

From lookings specs, MD250H would certainly be faster machine. But how much would depend on rider.

head-angle 24.5 on MD250H vs. 25.5 on Tianda
wheelbase = 48.4" vs. 52.0"
weight 198-lbs vs 216
power 34.5hp vs 27.5hp

Every tiny little bit adds up to fractions of second on every corner and straight. I don't have concrete numbers, but differences in those specs I suspect would result in 3-5s faster laptimes on most tracks favouring MD250H.

For non-pro racing, that's not whole lot and rider-skill ends up making larger differences than that. For example, guy that finished ahead of me in my 1st AFM race was faster than me by 10s/lap. Now I'm 7s/lap faster than him, both on stock Ninja 250s with same mods allowed by rules.

I think for price, that TDR300 is great value! Best deal on track bike anywhere really. Maybe upgrade it to Ninja 300 engine or Banshee 350.

I'm looking at the specs for that TDR300 and it looks like a lot of bike for the money.

I would love to have one. Would probably work great at some of the kart tracks I go to, normally with my Z125 mini.

The MD250 does sound like the better bike. Every used MD250 I’ve can across has been about $1k more a new TDR300 though. I love little bikes but I hate all the compromises there are with our little ninjas. The super low center of gravity, low foot pegs, and low seat just suck for track use. Maybe I can stumble across a MD250 for a reasonable price one day or even one of these TDR’s if they prove reliable.
