TL;DR
These are two different products with two different jobs. The Rascal GT Drag Kit is a competition-grade kit built around the lightest possible chassis and race componentry. The FRP RMB Rebel is a complete drag roller with the drivetrain pitch already decided. Their headline weights — 22.5 lb and 57 lb — are not the same measurement, and comparing them directly is the single easiest mistake to make here.
Direct Answer
Pick the Rascal GT Drag Kit if you are building a competition bike, you want the lightest chassis and race-grade wheels and hubs, and you are happy to source a chain and rear sprocket yourself.
Pick the FRP RMB Rebel if you want a drag roller where the geometry and the drivetrain pitch are already settled, you would rather buy an engine than a parts list, and you want it now.
Both are rollers. Neither includes an engine or a clutch. The differences are in what else is decided for you, and in what you still have to buy afterward.
The Weight Numbers Are Not Comparable — Read This First
This is the part that trips people up, so it goes before the table.
Rascal GT publishes 22.5 lb. That figure is the frame and fork only. FRP publishes 57 lb. That figure is the complete roller — wheels, tires, brake, rotor, sprocket, grips and all. To compare them honestly you would have to add the Rascal GT's own wheel package, brake assembly, seat, bars and tank onto its 22.5 lb before you put the two numbers side by side.
Neither number is wrong. They are just answers to different questions. If a spec sheet gives you one number and no basis, the number is not usable yet — find out what was on the scale.

Where the Rascal GT Is Genuinely Ahead
Two things, and they are real.
The chassis is lighter, and deliberately so. Honeycomb cut-outs and a dual down tube are a race solution to a race problem. If your build is about chasing a number on a slip, a lighter frame is a lighter frame, and FRP does not publish a frame-only figure to argue with it.
It includes a fuel tank and race componentry FRP does not. A 10 in aluminum cylinder tank, Douglas DWT wheels and GPS Racing billet hubs are in the box. On the RMB Rebel the fuel-tank holes are drilled but the tank is yours to buy, and the wheels are aluminum-hub units rather than a race wheel package.
If those are the things you are optimizing for, that is the kit — and the honest answer is that it is not the RMB.
Where the RMB Rebel Is Ahead
Shop the 420 chain, clutch & sprocket kit →
The drivetrain pitch is already decided. The RMB Rebel arrives with a 420 pitch, 41T rear sprocket fitted. The Rascal GT does not include a rear sprocket, so the pitch decision — and then a matching chain and clutch sprocket — is still ahead of you. If you want the reasoning behind running 420 on a 212-class engine, the #35 vs #420 chain guide covers it, and the sprocket size guide covers gearing after that.
The wheelbase is published. 43.4 in, stretched from the factory. Rascal GT publishes a 41 in frame length but not a wheelbase, and frame length and wheelbase are not the same thing. If stance matters to your build, you can plan around FRP's number today.
The engine list is broader and more specific. The RMB Rebel names the Honda GX-clone bolt pattern outright: Predator 212 Hemi or non-Hemi, GX160, GX200, Titan TX200, Tillotson 212, and 196-224cc clones with a 3/4 in shaft. Briggs Animal and racing Briggs engines use a different mounting pattern and need an adapter plate — that is true of most GX-pattern chassis, and it is worth knowing before you buy an engine you cannot bolt down.
It is in stock. As of July 2026 the Rascal GT Drag Kit is listed out of stock on GoPowerSports' own site while the Cruiser Kit and the bare Rascal GT frame are not. That will change when they restock, but it is where things stand today.
Not Building for Drag?
Then neither of these is the right starting point.
Shop the GMB100 upgraded frame →
Drag geometry is a trade. A stretched wheelbase and a narrow-front / wide-rear stance are built to go straight and hook, and they cost you turning. For a general-purpose 79cc to 212cc build the GMB100 Upgraded Frame is the platform — a bare frame with a universal engine plate, hydraulic brakes pre-installed and seven finishes, rated to 220 lb, no welding required.
If you are still working out which format you need at all, the mini bike roller frame build checklist lists what a roller needs before it runs, and the Mini Bike Frames & Roller Kits page lays out the whole FRP lineup.
FAQ
Is the RMB Rebel heavier than the Rascal GT?
The published numbers do not answer that. FRP's 57 lb is the complete roller, including wheels, brake, rotor, sprocket and grips. GoPowerSports' 22.5 lb is the frame and fork only. To compare them you would have to add the Rascal GT's wheels, brake, seat, bars and tank to its figure first.
Does the Rascal GT Drag Kit come with a rear sprocket?
No. Per GoPowerSports' own listing, the drive chain and sprocket are among the parts you supply. The RMB Rebel ships with a 420 pitch, 41T rear sprocket already fitted, so you supply the chain and a matching clutch or torque converter sprocket.
Which one includes a fuel tank?
The Rascal GT Drag Kit includes a 10 in aluminum cylinder tank. The RMB Rebel does not — it has dedicated fuel-tank mounting holes drilled, but the tank is a separate purchase.
What engines fit each one?
The RMB Rebel uses the Honda GX-clone bolt pattern: Predator 212, GX160, GX200, Titan TX200, Tillotson 212 and 196-224cc clones with a 3/4 in shaft. Briggs Animal needs an adapter plate. GoPowerSports lists the Rascal GT as a small-block platform and recommends a Tillotson 225.
Can I still buy a Rascal GT Drag Kit?
As of July 2026 it is listed out of stock on GoPowerSports' site, while their Rascal GT Cruiser Kit and bare Rascal GT frame are listed in stock. Availability changes — check their listing directly rather than relying on this page for that.
Safety Note
Both of these are race-oriented rolling chassis for off-road and track use only. Neither is street legal. Assemble correctly, check chain line and brakes before every session, ride with proper gear, and follow local rules.
