Engine and vehicle manufacturers, as well as owners, operators, and rebuilders of these vehicles, and all other persons, must observe the requirements and prohibitions in part 1068 of this chapter and the requirements of the Act. The compliance provisions in this subpart apply only to the vehicles and engines we regulate in this part.
(a) You may certify ATVs with engines that have total displacement of less than 100 cc to the following exhaust emission standards instead of certifying them to the exhaust emission standards of subpart B of this part:
(1) 25.0 g/kW-hr HC + NOX, with an FEL cap of 40.0 g/kW-hr HC + NOX.
(2) 500 g/kW-hr CO.
(b) You may certify off-highway motorcycles with engines that have total displacement of 70 cc or less to the following exhaust emission standards instead of certifying them to the exhaust emission standards of subpart B of this part:
(1) 16.1 g/kW-hr HC + NOX, with an FEL cap of 32.2 g/kW-hr HC + NOX.
(2) 519 g/kW-hr CO.
(c) You may use the averaging, banking, and trading provisions of subpart H of this part to show compliance with this HC + NOX standards (an engine family meets emission standards even if its family emission limit is higher than the standard, as long as you show that the whole averaging set of applicable engine families meet the applicable emission standards using emission credits, and the vehicles within the family meet the family emission limit). You may not use averaging to meet the CO standards of this section.
(d) Measure steady-state emissions by testing the engine on an engine dynamometer using the equipment and procedures of 40 CFR part 1065 with either discrete-mode or ramped-modal cycles. You must use the type of testing you select in your application for certification for all testing you perform for that engine family. If we test your engines to confirm that they meet emission standards, we will do testing the same way. If you submit certification test data collected with both discrete-mode and ramped-modal testing (either in your original application or in an amendment to your application), either method may be used for subsequent testing. We may also perform other testing as allowed by the Clean Air Act. Measure steady-state emissions as follows:
(1) For discrete-mode testing, sample emissions separately for each mode, then calculate an average emission level for the whole cycle using the weighting factors specified for each mode. In each mode, operate the engine for at least 5 minutes, then sample emissions for at least 1 minute. Calculate cycle statistics for the sequence of modes and compare with the specified values in 40 CFR 1065.514 to confirm that the test is valid.
(2) For ramped-modal testing, start sampling at the beginning of the first mode and continue sampling until the end of the last mode. Calculate emissions and cycle statistics the same as for transient testing.
(3) Measure emissions by testing the engine on a dynamometer with one or more of the following sets of duty cycles to determine whether it meets applicable emission standards:
Table 1 of §1051.615—6-Mode Duty Cycle for Recreational Engines
2Percent torque is percent of maximum torque at the commanded test speed.

(4) During idle mode, operate the engine at its warm idle speed as described in 40 CFR 1065.510.
(5) For the full-load operating mode, operate the engine at wide-open throttle.
(6) See 40 CFR part 1065 for detailed specifications of tolerances and calculations.
(e) All other requirements and prohibitions of this part apply to these engines and vehicles.
[67 FR 68347, Nov. 8, 2002, as amended at 70 FR 40503, July 13, 2005; 73 FR 59254, Oct. 8, 2008]
(a) We may grant you an exemption from the standards and requirements of this part for a new recreational vehicle on the grounds that it is to be used solely for competition. The provisions of this part other than those in this section do not apply to recreational vehicles that we exempt for use solely for competition.
(b) We will exempt vehicles that we determine will be used solely for competition. The basis of our determinations are described in paragraphs (b)(1), (b)(2), and (c) of this section. Exemptions granted under this section are good for only one model year and you must request renewal for each subsequent model year. We will not approve your renewal request if we determine the vehicles will not be used solely for competition.
(1) Off-highway motorcycles. Motorcycles that are marketed and labeled as only for competitive use and that meet at least four of the criteria listed in paragraphs (b)(1)(i) through (vi) of this section are considered to be used solely for competition, except in cases where other information is available that indicates that they are not used solely for competition. The following features are indicative of motorcycles used solely for competition:
(i) The absence of a headlight or other lights.
(ii) The absence of a spark arrestor.
(iii) The absence of manufacturer warranty.
(iv) Suspension travel greater than 10 inches.
(v) Engine displacement greater than 50 cc.
(vi) The absence of a functional seat. (For example, a seat with less than 30 square inches of seating surface would generally not be considered a functional seat).
(2) Snowmobiles and ATVs. Snowmobiles and ATVs meeting all of the following criteria are considered to be used solely for competition, except in cases where other information is available that indicates that they are not used solely for competition:
(i) The vehicle or engine may not be displayed for sale in any public dealership.
(ii) Sale of the vehicle must be limited to professional racers or other qualified racers.
(iii) The vehicle must have performance characteristics that are substantially superior to noncompetitive models.
(c) Vehicles not meeting the applicable criteria listed in paragraph (b) of this section will be exempted only in cases where the manufacturer has clear and convincing evidence that the vehicles will be used solely for competition.
(d) You must permanently label vehicles exempted under this section to clearly indicate that they are to be used only for competition. Failure to properly label a vehicle will void the exemption for that vehicle.
(e) If we request it, you must provide us any information we need to determine whether the vehicles are used solely for competition.
[67 FR 68347, Nov. 8, 2002, as amended at 70 FR 40504, July 13, 2005]
(a) We may permit you to produce up to 600 snowmobiles per year that are certified to the FELs listed in this section without new test data, as long as you meet all the conditions and requirements in this section.
(b) You may certify these snowmobiles with FELs of 560 g/kW-hr for CO and 270 g/kW-hr for HC (using the normal certification procedures).
(c) The emission levels described in this section are intended to represent worst-case emission levels. You may not certify snowmobiles under this section if good engineering judgment indicates that they have emission rates higher than these levels.
(d) Include snowmobiles you produce under this section in your averaging calculations under Subpart H of this part.
(e) You must meet all the requirements of this part, unless the regulations of this part specify otherwise.
(a) If you are a small business (as defined by the Small Business Administration at 13 CFR 121.201) that manufactures recreational vehicles, but does not otherwise qualify for the small-volume manufacturer provisions of this part, you may ask us to designate you to be a small-volume manufacturer. You may do this whether you began manufacturing recreational vehicles before, during, or after 2002.
(b) We may set other reasonable conditions that are consistent with the intent of this section and the Act. For example, we may place sales limits on companies that we designate to be small-volume manufacturers under this section.
[67 FR 68347, Nov. 8, 2002, as amended at 73 FR 59255, Oct. 8, 2008]
You may ask to exempt custom-designed off-highway motorcycles that are substantially similar to highway motorcycles under the display exemption provisions of 40 CFR 86.407-78(c). Motorcycles exempt under this provision are subject to the restrictions of 40 CFR 86.407-78(c) and are considered to be motor vehicles for the purposes of this part 1051.
[69 FR 2445, Jan. 15, 2004]
The following provisions apply if you identify the name and trademark of another company instead of your own on your emission control information label, as provided by §1051.135(c)(2):
(a) You must have a contractual agreement with the other company that obligates that company to take the following steps:
(1) Meet the emission warranty requirements that apply under §1051.120. This may involve a separate agreement involving reimbursement of warranty-related expenses.
(2) Report all warranty-related information to the certificate holder.
(b) In your application for certification, identify the company whose trademark you will use.
(c) You remain responsible for meeting all the requirements of this chapter, including warranty and defect-reporting provisions.
[70 FR 40504, July 13, 2005, as amended at 73 FR 59255, Oct. 8, 2008]
A certificate of conformity is no longer valid for a vehicle if the vehicle is modified such that it is not in a configuration covered by the certificate. This section applies if such modifications are done to convert the vehicle to run on a different fuel type. Such vehicles may be recertified as specified in this section if the original certificate is no longer valid for that vehicle.
(a) Converting a certified new vehicle to run on a different fuel type violates 40 CFR 1068.101(a)(1) if the modified vehicle is not covered by a certificate of conformity.
(b) Converting a certified vehicle that is not new to run on a different fuel type violates 40 CFR 1068.101(b)(1) if the modified vehicle is not covered by a certificate of conformity. We may specify alternate certification provisions consistent with the requirements of this part. For example, you may certify the modified vehicle for a partial useful life. For example, if the vehicle is modified halfway through its original useful life period, you may generally certify the vehicle based on completing the original useful life period; or if the vehicle is modified after the original useful life period is past, you may generally certify the vehicle based on testing that does not involve further durability demonstration.
(c) Vehicles (or engines) may be certified using the certification procedures for new vehicles (or engines) as specified in this part or using the certification procedures for aftermarket parts as specified in 40 CFR part 85, subpart V. Unless the original vehicle manufacturer continues to be responsible for the vehicle as specified in paragraph (d) of this section, you must remove the original manufacturer's emission control information label if you recertify the vehicle.
(d) The original vehicle manufacturer is not responsible for operation of modified vehicles in configurations resulting from modifications performed by others. In cases where the modification allows a vehicle to be operated in either its original configuration or a modified configuration, the original vehicle manufacturer remains responsible for operation of the modified vehicle in its original configuration.
(e) Entities producing conversion kits may obtain certificates of conformity for the converted vehicles. Such entities are vehicle manufacturers for purposes of this part.
