YZ125 lowering 2015 question for Todd's son

"I just bought my son a new 2015 YZ125. The bike is strictly for racing motocross, and he is a novice class rider presently. He is about 125 pounds but on the shorter side. What link, #1 or #2, do you recommend, and how much can I expect the bike to lower with each link? He rode his 85 fast and hard, and I expect he'll eventually do the same with the 125."

We replied "We made the #2 specifically for riders like your son. Yes, the #1 lowers the bike more (1.5") which is great especially on the start line (most use blocks anyway), but we made the #2 for my nephew who at the time was 100 pounds and about 5'4", but he was insanely fast coming off a super mini. The #2 only lowers the rear about 1/2" but the YZ handled so much better especially when the tracks got rougher and/or second moto. So it's not a true lowering link; that's why we call it the RACE YamaLink. Today we sell the #2 to tall YZ racers not just the slightly height impaired.

If you would've said your son was a casual beginner off-road rider and NEVER raced MX we'd go #1. But an aggressive in shape fast kid always chooses the short travel YamaLink aka #2."
