A full rebuild kit!
I bought the kit for a 2003 CR125 which had burned up the crankshaft. The Wrench Rabbit kit is a box with almost all the parts you'll need- piston, crankshaft, all the bearings, gaskets, o-rings, water pump seals, it's all there except for two important seals- the kit did not include the seal on the outer surface of countershaft spacer, and also not the exhaust flange seal.

The parts themselves are of very good quality. HotRod crankshaft, Vertex piston, etc.

I cannot comment to durability at this time as I haven't run the bike yet.

Very comprehensive kit, missing one thing
This really is the best kit on the market. The quality of the gaskets, seals, bearings, piston, crank, etc is all pristine and high quality. The kit is the most complete kit I could fine besides just buying a whole new motor.

I do want to point out one thing it does not include for anyone else who may be purchasing for their YZ250, and that is governor bearings. (OEM Part# 93300-60814-00)

Everything I needed for my first rebuild
Came with everything I needed to complete my first full engine rebuild. Having everything in one package made the rebuild a breeze. Easy to stay organized and I was surprised with how well it was packaged for shipment. Only items that I had to buy that was not in this kit was a washer for the clutch hub and a snap ring for the kick start idle gear. To top off my engine build I added the tusk comp clutch with heavy duty springs. Couldn’t be more pleased with the products and as always RM customer service is second to none

I found the Wrench Rabbit kit to be the best value and most convenient way to get everything needed when doing a full engine rebuild.
Initially I spent hours looking for everything I thought needed to rebuild my sons engine. After making a list and pricing out all the individual parts I came across the Wrench Rabbit kit. Not only did it have everything on my list, it also included the transmission bearing set, as well as the water pump bearing and seal. These are items I had not considered. In the end, I found the Wrench Rabbit kit to be the best value and most convenient way to get everything needed when doing a full engine rebuild.

Received kit for 2000 Honda cr125r currently have a B cylinder. Service manual mentions a an b pistons but kit came with a c piston? C piston is slightly larger than A and B...any reason to worry about running c piston in a b cylinder? Why not offer a or b as the actual replica piston?
JASON S on Dec 22, 2017
How many hours can this crank take before the rod snaps and ruins the block?
Dylan O on Mar 28, 2019
BEST ANSWER: Depends on your jetting/cylinder/head work and the way you ride. But I run a big bore with porting and head work with vp 110 and have 60 hours on the crank with no play up and down and no more side to side play sense day one. No visible wear yet. Confident it will last at least 150 hours
does this kit come with a cylinder?
Cassidy A on May 21, 2017
BEST ANSWER: No, this kit will only come with internal engine parts.

Kit Includes:
-Vertex Piston Kit (standard compression piston, rings, pin and clips)
-Hot Rods Heavy Duty crank (stock stroke- includes wrist pin bearing for two strokes)
-Hot Rods main bearing/seal kit
-Hot Rods transmission bearing kit (includes transmission bearings, output shaft collar and sprocket lock washer)
-Hot Rods counter balancer bearing kit

Is this kit durable? And how is it compaired to hot rod or weisco kit ?
Enrique o on Feb 4, 2019
BEST ANSWER: Yes the kit is probably the best to do a rebuild with. It’s came with all bearings and seals needed. Everything was hot rods brand except for case seals ,I believe where weisco and the piston was weisco brand. I was doing a full engine rebuild and a big bore and porting, so I did not use the piston included. This kit does come with every piece needed. Hands down 5 out of 5 for price and craftsmanship. know you need to order early because Rocky Mountain does not keep them in stock on location. Wrench rabbit them self builds your package at there warehouse and ships out. I ended up paying for express shipping to recive it in a week. Normally I believe it takes between 2-3 weeks to receive. Now the price from buying through Rocky Mountain was about 50-70 dollars cheaper. So basically doing express shipping evened it out. Idk why the wrench rabbit company doesn’t just lower thier price to bring in more customers to their website. The crank is still good as new 35 hrs later on bike and I have zero leaks between oil and coolant. Crank bearings are solid to as is the crank seals. As all other bearing I’m not sure as I’m not cracking back into the bottom end until either something breaks or about 100 hrs of ride time.
Does this come with the transmission bearing as well ?G
Christopher G on Jan 14, 2019
BEST ANSWER: The Wrench Rabbit kit I ordered had everything to perform a complete rebuild including the transmission bearings. In my opinion the kit is the cheapest, most convenient way to go.
is this product worth buying?
Trenton Y on Feb 21, 2017
BEST ANSWER: Yes, there may be minor little pieces you may have to buy that are left out like copper washers and c-clips that the manufacturer of the motorcycle recommend replacing instead of reusing but other than that it's all there. Built my kx450f with this kit and put 15 hard hours on it so far without any issues.

Carson L on Jan 22, 2020
