### ⭐⭐⭐⭐⭐ 







  
  
    Makes the chain tighter.
  

*by Z***. on Reviewed in the United States on 28 September 2022*

Chain is perfectly tight now. But most importantly, my 3 year old is now clearing the 140’ triple and throwing knack knacks because of this amazing performance upgrade!

### ⭐⭐⭐⭐⭐ 







  
  
    Razor replacement parts
  

*by A***R on Reviewed in the United States on 24 August 2016*

Sold out on the first few web sites I searched.  Product was in stock and delivered in about a week.  No issues.  I probably could have saved a few bucks by just ordering the spring, but changed everything out and should be good for another year or so.  Spring on the original Razor 650 broke and chain will not stay on.  I was surprised at how important this piece is.

### ⭐⭐⭐⭐⭐ 







  
  
    Great for the price
  

*by S***O on Reviewed in the United States on 30 June 2021*

Works as anticipated, installed on a razor sx500
