You need a fuel injected vehicle if you don't want to wait for the engine to warm up prior to operation.
Carburetted machines require extended warm ups vs fuel injected, but fuel injectedHonda has always been known as requiring a longer warm up than others - Yamaha is renown for easy starting and fast warm-up, Suzuki is one of the hardest to start cold and requires a longer warm up than Honda, Kawasaki starts easy but is fidgety during warm up.
I have a 2004 CRF250X - it does not have a choke like the TRX - it has a bypass fuel enrichening cold starting circuit and the Keihin FCR carb also has an accelerator pump. I typically start the engine with the enrichener fully open and let the engine run at high idle while I change into my race gear - when ready to race, I ride with the bypass starter open until I find a convenient place to reach down and close the valve. Unlike the choke your carb is equipped with, the bypass starter is ineffective above 1/4 throttle opening, so unless I let the throttle close to less than 1/4, the by pass starter does not effect the operation. Average warm up of my CRF is 5 to 10 minutes.
