You know it's funny when all the bike advancements are used to justify rekluses. Power valves and suspension improved on deficiencies in the bike, a rekluse deals with a deficiency in the rider whether it be skill, strength or endurance. that is an excellent point, but i think in your case it would also be dealing with a deficiency or shortcoming in the bike. an mx bike is typically not geared well for gnarly offroad (and it's even worse on a 125 with very little low-end). a rekluse allows you to still run the way-too-tall 1st gear and get away with it. this is something i have considered for my 250sx, but instead i just swap between a 13t for woods and a 14t for dezert. i also have a 12t for 5moh type stuff, but then tresa has to wait too m u ch since her bike goes 20 mph faster than my bike likes to go with that 12t on it, lol.
