Royal enfield desert storm

Hi, both Royal Enfield Classic 500 and Classic Desert Storm are having the same reliable 499 cc, Air cooled, Single Cylinder, 4-stroke, Twinspark, Digital Electronic Fuel ignition, aluminum UCE engines with 27.2 bhp @ 5250 rpm of power and has 41.3 Nm @ 4000 rpm of torque and gives mileage of around 25 to 32 kmpl depending upon the riding style and conditions.
Where as Royal Enfield Classic 350 has reliable 346cc, Air cooled, Single Cylinder, 4-stroke, Twinspark, Transistorised Coil ignition (TCi), aluminum UCE engine with 19.8 bhp @ 5250 rpm of power and has 28 Nm @ 4000 rpm of torque and gives mileage of around 34 to 40 kmpl depending upon the riding style and conditions and costs 117,900 rs on road Mumbai.
Regarding Classic 500 and Classic Desert Storm, has more maintenance costs, less mileage and less resale value when compared to Classic 350. So better think about it and take a wise decision.

350 = 40 -47 kmpl
500/Desert Storm = 25-35 kmpl
None of these bikes is good for long term because twin spark engines do not last too long.
