This is not applicable in all cases, but in many cases a reduction of weight on the rider is beneficial to 'overall' performance.

On the rider or "of the rider"? Like in horse racing they choose short and lanky guys to be the jockeys? I think Pesi Shroff weighs something like 48 kgs or less.

In what way?
Everything proposed in the thread is tampering with a stock bike.
Enfield themselves offer a model with 18" wheels. dont recall which one. It dosent really hurt anything.

You can also look for alloy rims but that would spoil the look. BMW uses alloy rims and steel spokes on their DP bikes. Use an RD style aluminum/steel fork and maybe some Ohlins Al shocks in teh back. Tank is a challenge but the GpC racing guys have it I think. Mudguards should be easier. Do the easy stuff like handlebar and crash guard that can be done with tubing.
