I replaced the rear shock absorber on my daughters Hanma 110cc Utility with a 10" Front shock absorber, and it's a %100 Night & Day difference. My daughter is 8 years old and 60 lbs, The stock rear suspension with her weight on the machine was similar to having no suspension at all, now its actually responsive with the front shock in place. Simple mod only had to swap the bushings from the rear shock to the front. I also added 3" utilizing wheel spacers. Feels like a name brand mini atv now, and my daughter is alot more confident while she is riding.
